Abstract

A variety of penta-2, 4-dienyltitanium complexes including those having a functional group were readily prepared from a divalent titanium reagent, Ti (O–i-Pr) 4/2i-PrMgCl, and penta-1, 4-dien-3-ol or penta-2, 4-dien-1-ol derivatives, and the organotitaniums thus prepared reacted with aldehydes and ketones smoothly to afford the corresponding penta-1, 4-dien-3- yl carbinols highly predominantly in excellent yield.
