Reaction of acyl isocyanates with pyridine derivatives

Abstract

Trichloroacetyl isocyanate reacts with 2- and 4-picolines to form substituted trichloroacetylamidates. Benzoyl isocyanate forms a dimer in the presence of picolines. Depending on the nature of the solvent, trichloroacetyl isocyanate adds to 4-vinylp'yridine either at the vinyl group or at the ring nitrogen atom. © 1985 Plenum Publishing Corporation.
