Abstract

Old Selenium Heterocycles Revisited: Synthesis, Spectroscopic, and Structural Characterization of N-Acyl-1,3-selenazol-2(3H)-imines and 5-Acyl-1,3-selenazol--2-amines from Acylselenourea Derivatives. -Reaction of 1-acyl-3-arylselenoureas (I) with phenacyl bromides provides access to selenazol-imines (III), whereas the analogous reaction of 3,3-disubstituted 1-acylselenoureas (IV) affords 5-acylselenazol-2-amines (V). -(MOHR, F.; J.
