Focusing on the Elements - Colors and Chemical Names (1)

Kentaro Sato
Vivid, diverse, and changeable colors of chemicals lured many of us stepping into the field of chemistry as young students. There are indeed a number of elements and compounds that display beautiful colors. Some of them are used as synthetic dyes and were a major part of the early development of chemical industry. From litmus paper to state-of–the-art bioimaging technologies, color and chemical research always go hand in hand.
So not surprisingly, there are quite a few chemicals with names derived from their colorful appearances. In this article, let us look at some of the interesting examples.

A Novel Cyanation Reaction of Arenes Using Acetonitrile as a Cyano Source

Shen et al. have reported a novel cyanation reaction of arenes using acetonitrile as a cyano source. According to their results, the reaction proceeds through a tandem process producing aryl iodides (1) from a copper complex catalyst-promoted iodination of simple arenes with N-iodosuccinimide (NIS), and a subsequent cyanation reaction. In this reaction, it is presumed that the cyano source is generated via the formation of an acetonitrile-derived cyanomethyl group-substituted TEMPO intermediate (2) and a sequential C-CN bond cleavage by the action of copper complex catalysts and hexamethyldisilane. This cyanation-process using TEMPO, copper complex catalysts and acetonitrile as a cyano source is a safe and inexpensive synthetic method and its future development can be expected.


Product Highlight

A Useful Crystalline Trifluoroacetylating Reagent

(Trifluoroacetyl)benzotriazole (1) is a crystalline trifluoroacetylating reagent and used for the direct trifluoroacetylation of amines and alcohols without any base. The trifluoroacetylation with amines is carried out at room temperature in good yields when primary and secondary amines and low nucleophilic aniline derivatives are employed as reactants. On the other hand, the trifluoroacetylation with alcohols proceeds with refluxing THF. All primary and secondary alcohols and phenols including such a high-acidic phenol as 4-nitrophenol are available for this trifluoroacetylation. 1 has advantages of a crystalline solid and is easy to weigh, and can be used for the direct introduction of a trifluoroacetyl group under mild conditions. Thus, 1 is a useful trifluoroacetylating reagent.
