Buta-2,3-dienylstannanes, effective reagents for regioselective buta-1,3-dienylation of aldehydes and acetals
Abstract
Two buta-2,3-dienylstannanes, 1-tri-n-butylstannylbuta-2,3-diene and 1-triphenylstannylbuta-2,3-diene, have been prepared and shown to react with aldehydes and acetals under Lewis acid catalyzed conditions producing (buta-1,3-dien-2-yl)methanol derivatives in high yields.
