Date Feb. 1, 1996Vinyl carbamate compounds are prepared by reacting appropriate secondary amines with carbon dioxide and acetylenically unsaturated compounds in the presence of a compound of a metal from the platinum group, in particular a ruthenium compound, with either one of the two process steps (a) and (b) or, preferably, both being carried out: (a) the acetylene compound is reinjected during the reaction; (b) the reaction is carried out in the presence of a tertiary amine.
