The reduction of alkynols with LiAlH 4 in diglyme is a long known process leading to the formation of (E)-alkenols. We have, by serendipity, found that, in the presence of a catalytic amount (10%) of Cp 2 TiCl 2 , the stereoselectivity of the reaction is reversed, leading to the selective formation

Recently, the reduction of alkenes and alkynes by the reagent, LiAlH4-transition metal halide has been reported. 132 Although one might assume that this reaction proceeds via hydrometallation, deuterolysis shows that only titanium compounds of the first row transition metals are effective in the for
