(Figure Presented) A novel method for the formation of isolated C - C bonds was developed via a ruthenium-catalyzed decarbonylative addition of aliphatic aldehydes and alkynes. An unprecedented complete switch of chemoselectivity from aromatic aldehydes to aliphatic aldehydes was observed simpl y by using tri(2,4,6-trismethoxyphenyl)phosphine as ligand. A synthesis by this method of an insect sex pheromone was demonstrated.

Alkylated olefins were directly synthesized in good yields by the deoxygenation reaction of epoxides with concomitant introduction of the alkyl group using lithium tetraalkylcerate.Styreneoxide and (1-naphtyl)ethyleneoxide gave terminal olefins, while ethyleneoxide replaced by alphatic substituent, 1,2-epoxy-4-phenylbutane, afforded internal olefin.The utility of the present method was demonstrated in the one-step synthesis of a sesquiterpene, dehydro-α-curcumene.
