Relative hemilabilities of H₂B(az)₂ (az = pyrazolyl, dimethylpyrazolyl, methimazolyl) chelates in the complexes [M(η-C₃H₅)(CO)₂{H₂B(az)₂}] (M = Mo, W)

The reactions of [M(η3 -C3H5)Br(CO)2(NCMe)2] (M = Mo, W) or [Mo(η3 -C3H5)Br(CO)2(PMe2Ph)2] with Na [H2B(mt)2] (mt = methimazolyl) affords the complexes [M(η3 -C3H5)(CO)2{κ3 -H,S,S’-H2B(mt)2}], the 3-centre, 2-electron B–H–M interaction of which was found to be inert with respect to opening under mild conditions, while more forcing conditions (heating with PMe2Ph) resulted in cleavage of the entire allyl and borate ligands to form [Mo(CO)3(PMe2Ph)3]. In contrast, the reaction...[Show more]
