Reactions of acyl isocyanates with disubstituted amides

Abstract

1. The benzoyl-and trlchloroacetyl isocyanates react with dimethylacetamlde and dimethylbenzamide to give substituted amidlnes. 2. The existence of hindered internal rotation around the {Mathematical expression} bond in the molecules of the obtained amidines was detected by NMR spectroscopy. © 1975 Plenum Publishing Corporation.
