Abstract
The alkylation, acetylation, and aroylation reactions of [M(N2)2(dppe)2](M = MO or W; dppe = Ph2PCH2CH2PPh2) by organic halides RX are shown to procede by the initial rate-determining dissociation of one N2 from the complex to form [M(N2)(dppe)2], addition of the halide through the halogen to the metal producing an un-stable intermediate, [M(N2)(RX)(dppe)2], homolysis of the carbon-halogen bond, and attack of the organic free radical generated on the remaining co-ordinated N2 to produce [Mo(N2R)X(dppe)2].Keywords
