Abstract

Decomposition of Branched Azo Esters 2395 a.-Aminonitriles were hydrolyzed with hydrochloric acid; only 2, 3, 3-trimethylbutyronitrile could not be hydrolyzed in this way for steric reasons. Concentrated sulphuric acid was used in this case, and the hydrolysis· of the transitionally formed amide was completed with dilute acid. The yields of azo esters by oxidative coupling of a.-amino esters varied from 27% to 31%. The compounds were ...
