【摘要】 <正> 我们根据文献制备了P-2.00-Ni催化剂,对一系列α,β-不饱和醛、酮、酯等化合物进行选择性催化还原。发现该催化剂对共轭碳碳双键具有很高的选择性,一般在90％以上。在这一工作的基础上,再利用饱和酮通过格氏反应,可合成七个新的叔醇化合物。 1 α,β-不饱和酮的合成 合成的α,β-不饱和酮有2-甲基丙烯基,苯乙烯基乙基酮,2-亚环戊基环戊更多还原

【Abstract】 Some new tert-alcohols were synthesiaed. They 2,4-dimethyl-4-undecanol; 2, 4-dimethyl4-decanol; 3-ethyl-1-phenyl-3-pentanol; l-n-butyl-2-cyclopentyl-cyclopentanol; 1-ethyl-2-benzyl cyclohexanol; 3-ethyl-1, 5-diphenyl-3-pentanol; I-phenyl-3-petanol and the synthetic steps used can be summarized as follows:The aldol condensation→unsaturated ketonessaturated ketones→t-alcohols.The yields of the hydrogenation step show that the catalyst P-2. 00-Ni is very suitable for the preparation of saturated ketones from the related unsaturated ketones.更多还原
