SOLVOLYTIC CLEAVAGE OF ALKENYLPENTAFLUOROSILICATES CATALYZED BY COPPER(II) ACETATE. A STEREOSELECTIVE SYNTHESIS OF (E)-ALKENYL ETHERS FROM ALKYNES

Tamao, Kohei,Kakui, Toshio,Kumada, Makoto

, p. 4105 - 4108 (1980)

(E)-Alkenylpentafluorosilicates, obtainable from acetylenes via hydrosilylation-silicate formation, react with alcohols in the presence of a catalytic amount of copper(II) acetate under an atmosphere of air (oxygen) at room temperature to form (E)-alkenyl ethers stereoselectively in satisfactory yields.Similar reaction with water gives aldehydes.
