The reaction of cyclic amides with acetylene under low pressure, using ruthenium-phosphine catalysts, afforded a broad variety of N-vinylated amides including (azabicyclic) lactams, oxazolidinones, benzoisoxazolones, isoindolinones, quinoxalinones, oxazinanones, cyclic urea derivatives (imidazolidinones), nucleobases (thymine), amino acid anhydrides and thiazolidinone.

Process to produce N-vinyl compounds by homogeneous catalysis, wherein acetylene is reacted with a cyclic compound comprising a cyclic compound having at least one nitrogen as ring member, bearing a substitutable hydrogen residue (cyclic compound C), in a liquid phase in the presence of a ruthenium complex comprising at least one phosphine as ligand (RuCat).
