介绍了一种由3-甲氧基羰氧基-1-炔经甲酸铵氢解制备1，2-二烯的有效方法。3-甲氧基羰氧基-1-炔是通过乙炔镁与酮或醛加成，然后用氯甲酸甲酯淬灭而制备的。
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.
