catalysts and an additive, sodium hydroxide, on the catalytic hydrogenation of benzalacetophenone oxide (I) have been studied for the purpose of elucidating the selectivity of the catalysts on the hydrogenation. The catalytic hydrogenation over palladium or Raney nickel led to the formation of the hydroxyketones as the primary products resulting from the hydrogenolysis of the epoxide ring. 1,3-Diphenylpropane-1
为了阐明催化剂对氢化的选择性,已经研究了催化剂和添加剂氢氧化钠对苄基苯乙酮氧化物 (I) 催化氢化的影响。钯或阮内镍上的催化氢化导致羟基酮的形成,作为环氧化物环氢解的主要产物。1,3-二苯基丙烷-1,2-二醇(III)是通过钯催化加氢得到的,而1,3-二苯基丙烷-1,3-二醇(VI)和III是在阮内镍上得到的。在基本条件下,III 主要生产甚至超过 Raney 镍。在氧化铂上,2,3-epoxy-1,3-diphenylpropan-1-ol (VIII) 是 I 的羰基氢化的主要产物。 在 VIII, 1 的氢解中,
