Hantzsch Dihydropyridine Synthesis Pyridine Synthesis. Name reactions honor the discoverers of groundbreaking chemical reactions or refinements of earlier known transformations in the way that many scientists have their names attached to an effect or a phenomenon, an equation, a constant, etc.

In some cases, the person whose name is associated with the reaction was not the first to discover the reaction, but instead managed to popularize it. Reaction names can also simply describe the reaction type, often by using the initials or referring to structural features.

As an example, a very important field in chemical synthesis is carbon-carbon bond formation, and a great many name reactions exist that describe such transformations.

In this field, the development of a procedure for using organomagnesium compounds by Victor Grignard led to totally new addition reactions that expanded the scope of organic synthesis tremendously. In a historical twist, Grignard was not the first to use such reagents but rather simplified the procedure by generating the highly reactive reagent in situ. This popularized the use of the related transformations, which had previously been quite tedious as the sensitive organomagnesium reagents needed to be prepared separately and stored.

What we now know as Grignard reagents are most often used in additions to carbonyl compounds that provide alcohols or other products in high yields, and this process is nowadays referred to as the Grignard reaction. In another important case, many C-C bond forming reactions are promoted by palladium catalysis, which results in a more efficient use of reagents and more readily accessible conditions.

An example is the synthesis of biaryl moieties, substructures that occur frequently in compounds of interest in medicinal chemistry. As an indication of how useful these reactions are, the named reactions for many variants of these palladium-catalyzed biaryl coupling reactions became current within just a few years after discovery, even during lifetime of the respective authors, such as Makoto Kumada, John Kenneth, or J. Stille and Akira Suzuki coupling.

Other chemists, who develop specific variants or improvements or hybrid conditions, have their names are appended as in the Kumada-Tamao-Corriu coupling. In addition to the use of the names of chemists, we also have groundbreaking reactions that come to be known by abbreviations of a descriptive name, such as "RCM" ring-closing metathesis or INOC intramolecular nitrile oxide cyclization.

We seldom use the name of the chemist who developed RCM Robert Grubbs to refer to the reaction, but his contribution is instead acknowledged by applying his name to the ruthenium-catalysts used.

Thus, we speak of the "Grubbs catalyst" or "2nd generation Grubbs catalyst". Besides names such as "RCM", some frequently used reactions are named for structural features of the precursor or product. Examples include the "aldol reaction" "aldol" is an abbreviation of a compound that contains both aldehyde and alcohol functionalities or the "pinacol rearrangement".

As mentioned above, name reactions are used to refer to groundbreaking reactions or the associated mechanisms or principles that are worthwhile knowing and keeping straight. Just as physicians must learn the names of organs and geologists the names of minerals, chemists or students of chemistry use name reactions as a way to organize their knowledge and communicate about chemical transformations.

In laboratory discussions, people very often use name reactions to refer to experiments they are running or the chemical problems they are investigating. The name reaction is a type of shorthand that avoids the need to give a lengthier explanation of the features of a particular transformation of interest. Mentioning the name reaction allows a knowledgeable listener to bring to mind the possible substrates, reaction conditions, or mechanistic details.

Everyone in the field is expected to know a basic set of name reactions by heart, and this makes discussions less time-consuming. In this way, name reactions have become part of the shared vocabulary of organic synthesis chemists. Such recognition can signal that a listener or job candidate has command of a particular area of chemistry. This means that he or she would be capable of understanding details of the synthetic routes in the work described, and could possibly develop alternatives.

For any chemistry major or pre-med student, this course is a requirement, either for a degree or for admittance into medical school or other graduate study; however, it need not be the torturous experience it is rumored to be. It can be survived, if not enjoyed, with the right approach. Typically, organic chemistry is taught over the course of two semesters or quarters. The first part introduces key concepts and a few reactions, while the second part elaborates on these concepts and introduces more many reactions. It is the second half, with all of the reactions, that often seems unmanageable. Indeed, the number of reactions discussed would be overwhelming to any student who tried simply to memorize them; however, to the student who understands the underlying mechanisms and principles, the number of reactions covered by the class will seem a lot more manageable.

The Jones Oxidation allows a relatively inexpensive conversion of secondary alcohols to ketones and of most primary alcohols to carboxylic acids. The oxidation of primary allylic and benzylic alcohols gives aldehydes. Jones described for the first time a conveniently and safe procedure for a chromium VI -based oxidation, that paved the way for some further developments such as Collins Reaction and pyridinium dichromate , which also enabled the oxidation of primary alcohols to aldehydes. The Jones Reagent is a mixture of chromic trioxide or sodium dichromate in diluted sulfuric acid, which forms chromic acid in situ. The alcohol and chromic acid form a chromate ester that either reacts intramolecularly or intermolecularly in the presence of a base water to yield the corresponding carbonyl compound:. Aldehydes that can form hydrates in the presence of water are further oxidized to carboxylic acids:. Some alcohols such as benzylic and allylic alcohols give aldehydes that do not form hydrates in significant amounts; these can therefore be selectively oxidized with unmodified Jones Reagent to yield aldehydes.

 Я не электрик. Позвони в технический отдел. - В куполе нет света.

По ее щеке скатилась слеза. - Что с тобой? - в голосе Стратмора слышалась мольба. Лужа крови под телом Хейла расползалась на ковре, напоминая пятно разлитой нефти. Стратмор смущенно посмотрел на труп, затем перевел взгляд на Сьюзан.

Он не собирался умирать. Он рассчитывал, сидя в испанском баре, услышать по Си-эн-эн пресс-конференцию об американском сверхсекретном компьютере, способном взломать любые шифры. После этого он позвонил бы Стратмору, считал пароль с кольца на своем пальце и в последнюю минуту спас главный банк данных АНБ. Вдоволь посмеявшись, он исчез бы насовсем, превратившись в легенду Фонда электронных границ.

Мидж Милкен явно чего-то не поняла. - Это многое объясняет, - настаивала.  - Например, почему он провел там всю ночь. - Заражал вирусами свое любимое детище. - Нет, - сказала она раздраженно.

Самое лучшее из того, что можно найти на рынке. - Должно быть, Танкадо держится в стороне от таких вещей, но всем известно, что он гений. Это культовая фигура, икона в мире хакеров. Если Танкадо говорит, что алгоритм не поддается взлому, значит, так оно и. - Но ведь для обычных пользователей они все не поддаются взлому.

Створки стали стремительно сближаться. Стратмор попытался их удержать, но не сумел. За мгновение до того, как они сомкнулись, Сьюзан, потеряв равновесие, упала на пол за дверью. Коммандер, пытаясь приоткрыть дверь, прижал лицо вплотную к узенькой щелке. - Господи Боже мой, Сьюзан, с тобой все в порядке.
