A useful preparative method for 1,2-dienes from 3-methoxy-carbonyloxy-1-alkynes by the palladium-catalyzed hydrogenolysis with ammonium formate is described. 3-Methoxycarbonyloxy-1-alkynes are prepared by the addition of magnesium acetylide to ketones or aldehydes, followed by quenching with methyl chloroformate.
