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.

在调查钯催化交叉偶联反应之间卤化物、乙叠叠,1小时-1,2,3-三唑为主品均获得.

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.

二烃芳烃是非常不稳定的组分，可聚合生凝胶。对于给定烃烷芳烃，氢化可以改善品质。
