Abstract The $Beta@-migratory insertion of olefins into metal-carbon bonds is recognized as a fundamental carbon-carbon bond forming process that is central to metal-catalyzed dimerization, oligomerization, and polymerization reaction. In this paper we have directly observed the first reversible overall {Beta}-alkyl elimination/allyl migratory insertion reaction. On the basis of the results of the labeling study and the kinetic investigation, we favor a mechanism for this process that involves simple methyl transfer with the intermediacy of a 16e{sup -} unsaturated intermediate. Further studies on the mechanism and scope of the {Beta}-alkyl transfer are being pursued. 28 refs.
