Reactions of M2(CO)8(μ-PPh2)2 (M = Mo or W) with BR3H- and LIR nucleophiles. Proton-induced cleavage of M-(μ-PPh2) bonds in binuclear anionic complexes

Reactions of M2(CO)8(μ-PPh2)2 (2, M = Mo or W) with 1 equiv of M′BR3H (M′ = Li or K; R = Et or sec-Bu) in THF proceed to [(CO)4M(μ-PPh2)M(CO)4-Scheme I (Chemical Equation Presented) (PPh2H)]- (3) and with 2 equiv of M′BR3H or LiAlH4, to [M2(CO)8(μ-PPh2)2]2- (4). Treatment of 4 with 1 equiv of CF3COOH in THF affords 3, whereas treatment of 3 with 1 equiv of CF3COOH yields cis -M(CO)4(PPh2H)2 and M-(CO)5(PPh2H) as major and minor products, respectively. Reactions of 2 with LiR (R = Me, n-Bu, and Ph) proceed regiospecifically to the equatorial isomers of [M2(CO)7-(COR)(μ-PPh2)2] -, which are alkylated by Me3O+BF4- to yield M2(CO)7[C(OMe)R] (μ-PPh2)2 (R = Me).
