光照下,以甲醇为氢源,以NiCl_2、Ni(OAc)_2或CoCl_2为催化剂,1-辛烯可以发生催化转移加氢反应,得到辛烷,主要副产物为双键异构的2-辛烯和3-辛烯.综合催化剂的加氢活性和产物辛烷的选择性,NiCl_2的催化效果最好,且NiCl_2的催化活性在293～333K范围内随温度升高而增加.以NiCl_2为催化剂,在反应体系中添加三正丁胺,于293K下反应24h,辛烷的产率由45%提高到65%,选择性由57%提高到70%.

The catalytic transfer hydrogenation of 1-octene to octane was carried out by using methanol as hydrogen donor and nickel and cobalt salts (such as NiCl_2, Ni(OAc)_2or COCl_2) as catalysts under irradiation. The major byproducts were 2-octene and 3-octene from isomerization of C=C. Among these catalysts, NiCl_2 was the most efficient in terms of octane yield and selectivity. Furthermore,the catalytic activity of NiCl_2 increased at the elevated temperature (293 ～ 333K). It was beneficial to the hydrogenation and restrained the side-reaction by adding tri-n-butylamine into reactive system, the yield of octane was increased from 45% to 65% and the selectivity of octane improved from 57% to 70% with NiCl_2 as catalyst at 293K after 24h.
