Metalated alkoxy- and alkylthioethenes readily add to isocyanates, and subsequent hydrolysis or alkylation of the adducts gives N-mono- and N,N-disubstituted 2-alkoxy- and 2-(alkylthio)acrylamides in up to 86% yield. The reactions with propyl and phenyl isocyanates do not stop at the stage of addition of one isocyanate molecule, and further addition leads to formation of linear and cyclic polyamide structures.
