Structure of 1-Acyl-2-alkyl-2-thiopseudoureas

Abstract

Deprotonation of 1-acyl-2-alkyl-2-thiopseudouronium salts has been shown to involve the loss of a proton from the 1 rather than the 3 position in those cases where both nitrogens carry at least one hydrogen atom. This results in an acylated 2-thiopseudourea in which the C=N is conjugated to the carbonyl group.
