Vinylation of pyridylcarboxamides with vinyltrimethoxysilane
A convenient method has been developed for the direct N-vinylation of pyridylcarboxamides with vinyltrimethoxysilane in the presence of copper(II) acetate and tetrabutylammonium fluoride. The yield of N-vinylamides depends on the nature of the starting amide and the solvent. The molecular structure of the products was confirmed by X-ray structural analysis.
