A stereoselective synthesis of ω-chlorodienals and ω-chlorodienones was described. Conjugated ω-chlorotrienals and trienones were also easily prepared via an efficient palladium-catalyzed rearrangement of allylic acetates.

An efficient stereocontrolled method for the synthesis of stereodefined conjugated polyenes (e.g., tetraenes, pentaenes, heptaenes) is described via Pd-catalyzed coupling reaction of terminal alkynes with vinyl chlorides.

omega-chlorodienals, omega-chlorodienones and 1,6-diacyl-1,3,5-hexatrienes were easily obtained from (E)- and (Z)-dichloroethylenes.

The reduction of various conjugated homopropargylic alcohols with sodium bis(2-methoxyethoxy) aluminium hydride (Red-Al®) in ether or THF is described. The reaction takes place cleanly and rapidly, under mild conditions, to give (E)-homoallylic alcohols stereoselectively in good isolated yields.
