摘要

It has previously been shown that the Mo=Mo bond in M2(OR)6 compounds is labile toward a number of oxidative-addition reactions. Treatment with halogens leads to the formation of Mo2(OR)6X4 (M-M) compounds (R = i-Pr, X = C1, Br and I), and addition of ROOR to formation of Mo2(OR)8 (R = i-Pr). Reaction with benzoyl peroxide gave a compound Mo2(OR)6(02CPh)2 (R = i-Pr), believed to contain a Mo-Mo bond. These earlier findings prompted us to continue to investigate oxidative-additions with simple X2 molecules. Reported here are studies involving molecular oxygen.
