SDS of cas: 39637-74-6《Direct Transformation of Arylamines to Aryl Halides via Sodium Nitrite and N-Halosuccinimide》 was published in 2018. The authors were Mukhopadhyay, Sushobhan;Batra, Sanjay, and the article was included in《Chemistry – A European Journal》. The author mentioned the following in the article:
A one-pot universal approach for transforming arylamines to aryl halides via reaction with sodium nitrite (NaNO2) and N-halosuccinimides (NXS) in DMF at room temperature under metal- and acid-free condition was described. This new protocol that is complementary to the Sandmeyer reaction, is suggested to involve the in situ generation of nitryl halide induce nitrosylation of aryl amine to form the diazo intermediate which is halogenated to furnish the aryl halide. And (1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) was used in the research process.
(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6 SDS of cas: 39637-74-6) is used as a resolving agent for alcohols as the diastereomeric esters by crystallization or chromatography and as a chiral derivatization reagent for determination of enantiomeric excess of alcohols and amines.
