Reduction of Cp2TiCl2 withsec-BuMgCl in THF gave a greenish deep brown solution which has been found to promote the reductive homocoupling of aromatic and α, β-unsaturated aldehydes to yield symmetrical 1, 2-diols with highthreo-selectivity.
用sec-BuMgCl在THF中还原Cp 2 TiCl 2产生浅绿色的深棕色溶液,已发现该溶液可促进芳族和α,β-不饱和醛的还原均偶联反应,从而生成具有高
硫选择性的对称1,2
-二醇。
