Reactions of benzoyl and trichloeoacetyl isocyanates with unsaturated ethers and sulfides

Abstract

1. The benzoyl and trichloroacetyl isocyanates react with enol ethers to yield products with a linear structure. 2. Trichloroacetyl isocyanate reacts with vinyl ethyl sulfides to give the 2 + 4-cycloaddition product, and with alkene sulfides of the RSCH=CHR′ type to give produots with a linear structure. Benzoyl isocyanate does not react with alkene sulfides. © 1974 Consultants Bureau.
