摘　　要：研究了光照下,异丙醇为氢源,非贵金属镍盐、钴盐催化不饱和醛/酮选择加氢反应.考察不同催化剂、催化剂用量、光照时间、碱性添加剂等对反应的影响,结果表明,光照条件下,以Co(OAc)2为催化剂,Na2C2O4为添加剂,温度为293K,光照24h,具有较好的活性和C=O选择性,不饱和醛/酮转化率达60%,不饱和醇选择性达62%.The catalytic transfer hydrogenation of unsaturated aldehydes and ketones,using 2-propanol as hydrogen donor,was carried out with cobalt and nickel salts catalysts under irradiation.The results showed that optimum condition was as fallows: under irradiation,reaction temperature 293k,reaction time 24h.Co(OAc)2 catalyst was possessed higher activity and C=O selectivity.The unsaturated aldehydes and ketones conversion and the selectivity to unsaturated alcohols reached 60% and 62% respectively.
