- W1971930442 abstract "ACRYLONITRILE reacts by addition with a variety of compounds that possess a reactive hydrogen atom to yield @-substituted propionitrile derivatives. This reaction is known as cyanoethylation (2, 4 ) . Many reports have indicated the addition of over 1300 compounds to acrylonitrile, but carboxylic acids reportedly failed to add in the presence or absence of acid or base catalyst (2,4). According to the best of our knowledge there is no report of the cyanoethylation of carboxylic acids, which would have provided a simple route for synthesizing @-substituted esters of hydracrylonitrile. Here we report the addition of some common carboxylic acids to acrylonitrile. Acetic, propionic, n-butyric, and isobutyric acids were added to acrylonitrile, giving the acetate, propionate, n-butyrate, and isobutyrate of hydracrylonitrile, respectively. A small amount of acrylamide was produced in every case. Reactions were conducted in a 50-ml. autoclave a t about 160 C. for 11 hours. The results are summarized in Table I. CHz =CHCN + RCOOH + RCOOCHzCHzCN" @default.
