The mechanism of the transfer hydrogenation and double bond migration of 1-hexene catalyzed by trans-Mo(N//2)//2(dpe)//2 (dpe equals Ph//2PCH//2CH//2PPh//2) has been studied. The stoichiometric reaction of 1-hexene with MoH//4(dpe)//2 suggests that the active species for the hydrogenation is MoH//2(dpe)//2 and that for the double bond migration it is Mo(dpe)//2. The double bond migration is suppressed in the hydrogenation of 1-hexene by molecular hydrogen, with the formation of a moderate amount of hexane. The result of the reaction of Mo(C//2H//4)//2 with 2-propanol suggests that dual pathways may be available for the transfer hydrogenation.
