Copper(II) acetate catalyzes the coupling of pinacol vinylboronates with silanols producing enol silyl ethers. This represents a novel enol silyl ether synthesis via formation of the C–O bond instead of the conventional Si–O bond. This also constitutes the first transition-metal-catalyzed oxidative cross-coupling with silanols.

A simple, highly stereoselective, and efficient method to obtain important attractants by the reduction of the triple bond in several E-enynes and hex-3-ynyl acetate by an activated Zn-Cu system is described. The stereoselectivity of the semireduction for the generation of a new (Z)-C=C bond was >98%. The substrates for the reduction reaction were obtained by new synthetic routes with an overall yield
