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.

The reaction of 2,4-pentadienyltrimethylstannane with α,β-unsaturated carbonyl compounds and p-quinones in the presence of Lewis acid affords the corresponding pentadienylated products in fair to good yield without formation of any Diels-Alder adduct.
