Convenient conditions are described for the preparation of 1,3-dienes by vinylstannane homocoupling using palladium(II)-catalysis with oxygen (or air) for Pd(0)/Pd(II) reoxidation; related homo-couplings, and cross-coupling reactions with allylstannane, are used to obtain 1,3-diynes, biaryls and 1,4-dienes.
描述了通过使用氧(或空气)进行钯(II)催化的乙烯基锡同聚反应制备1,3-二烯的便利条件;相关的同聚合反应以及与烯丙基锡的杂交偶联反应被用于获得1,3-二炔、二芳烃和1,4-二烯。
