Abstract

Tert-butylisocyanide inserts into the carbon-sulfur bond of α-cyano sulfides 2 - 6 to give thioimidates 10 - 14 . The thioimidates can also be obtained via the chlorine substitution of the tert-butylimino chloro sulfides 27 - 28 , which is a more general method. These thioimidates rearrange to E and Z isomers of N-vinylcarbamates 16 - 20 via a 1,3 C to N migration of the alkoxycarbonyl group.
