REACTION OF 2-ACYLPHENYLSELENOCYANATES WITH HYDROXYLAMINE AND PHENYLHYDRAZINE

2-Selenocyanatobenzophenone reacts with hydroxylamine to give 3-phenyl-1,2-benzisoselenazole N-oxide, the structure of which is indicated by polarographic reduction studies.The corresponding methyl and ethyl ketones react similarly but 3-methyl-2-selenocyanato acetophenone yields 4,8-dimethyl-2-imino-2H-1,3-benzoselenazine 3-oxide.Benzoselenopheno<3,2-b>indole is formed under mild conditions by action of phenylhydrazine on 2-selenocyanatoacetophenone. 12H-Quinoxalino<2,3-b><1,4>benzoselenazine is obtained by condensation of 2,3-dichloroquinoxaline with the Zn salt of 2-aminobenzeneselenol.

Regioselective halogenation of pyridinium N-(benzoazynyl) aminides as a way to produce N-benzyl-alpha-aminobenzoazines

The halogenation of pyridinium N-(benzoazynyl) aminides with N-halosuccinimides provides a mild and regioselective method to functionalize the negatively charged diazine moiety in most cases. In some examples, however, formation of other products is explained. Finally, alkylation of the exocyclic nitrogen and reduction of the N?N bond provides a simple and straightforward strategy to obtain functionalized N-benzyl-benzoazynyl-alpha-amines.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Quality Control of 2-Chloroquinoxaline, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1448-87-9, in my other articles.

Azole-N-acetonitriles as carbonyl synthons: A one-pot preparation of heteroaryl amides from halides

Azole-N-acetonitrile derivatives were utilized as synthons for an ambident carbonyl moiety via a strategy relying upon sequential base-mediated S NAr substitution of a 2-halo heterocycle, in situ oxidation, and amine displacement. This strategy allows prompt and efficient synthesis of N-containing heteroaryl amides directly from the corresponding halides via a one-pot process.
