Palladium-monophosphine complexes catalyse trans-selective arylative, alkenyla-tive, and alkylative cyclization reactions of alkynals [e.g. (68)] and alkynones with organoboronic reagents. These reactions afford six-membered allylic alcohols (69) (g) and/or their five-membered counterparts (70), whose ratios are dramatically affected... [Pg.334]
