alkyl sulfide fragmentation subsequent to its reaction with atomichydrogen is indicative of a reaction that proceeds via an early transition state. The competitive reduction of a series of substituted-benzyl alkyl sulfides was insensitive to the substituent on the aromatic ring (rho = -0.13, r = 0.99). The relative rates of fragmentation of a series of the substituted-benzyl alkyl sulfides gave a

Allylic alcohols, aldehydes, and triphenylphosphine participate in a one-pot process catalyzed by palladium, which is formally equivalent to the Wittig olefinization. It can be applied to both aliphatic and aromatic aldehydes. The resulting olefins which appear as mixtures of stereoisomers were fully hydrogenated. Two different mechanisms can account for the observed results.
