Cp_2TiCl_2-i-PrMgBr体系中影响炔烃加氢反应的结构因素

Structural factors affecting the hydrogenation of ethynes in the presence of Cp_2 TiCl_2-i-PrMgBr

研究了不同结构的炔烃及其在 Cp_2TiCl_2-i-PrM_gBr 存在下催化加氢反应的规律。讨论了反应中取代基的电子效应及炔烃的结构因素。

We have selected different ethynes and studied theirhydrogenation rules in the presence of Cp_2TiCl_2-i-PrMgBr.Itwas discovered that the velocity of hydrogenation increasedwith the increase in electric charge of the substituent.Thefactors of stereo-resistance are also important in the hydrog-enation.
