  are employed as electrophiles in the Pd-catalyzed cross-coupling with tosylhydrazones affording di-, tri-, and tetrasubstituted olefins. Fine tunning of the reaction conditions are required to accomplish the coupling successfully, including the addition of LiCl and the presence of small amounts of water. Under the optimized conditions, the reactions proceed with high yield and also high stereoselectivity

  芳基壬酸酯被用作亲电试剂，在钯催化的与甲苯磺酰azo的交叉偶联中得到二，三和四取代的烯烃。要成功完成偶联，需要对反应条件进行微调，包括添加LiCl和存在少量水。在最佳条件下，取决于偶联配偶体的性质，反应以高收率和高立体选择性进行。
