The rearrangement of various tertiary ethynylcarbinols to α,β-unsaturated aldehydes, catalyzed by polyvanadioorganosiloxanes, was studied, and the activation parameters of the reaction were determined.The structures of the side products were established, and proposals were made about the mechanism of their formation.Additives which suppress the side reactions were found.As a result the yields of the unsaturated aldehydes were increased significantly.
