1.While investigating Pd-catalyzed cross-coupling reactions between alkenyl halides and azides to yield vinyl azides, 1 H -1,2,3-triazoles were obtained as the main product.

1.在催化交叉偶联反应之间烯卤化物、乙烯产量叠叠,1小时-1,2,3-三唑为主产品均获得.

2.The diolefins and alkenyl aromatics are very unstable components which can give gums by polymerization.In giving olefins and alky aromatics the hydrogenation improves the product quality.

2.二烯烃和烯基芳烃是非常不稳定的组分，可聚合产。对于给定烯烃和烷基芳烃，氢化可以改善产品质量。
