Treatment of trans-[Mo(CNPh)(N2)(dppe)2] with aqueous HBF4 afforded an aminocarbyne complex, which was isolated as trans-[Mo(⋮CNHPh)(OCMe2)(dppe)2][BF4] (7) after crystallization of the crude product from acetone−hexane, whereas the reaction of trans-[Mo(CNBun)(N2)(dppe)2] with [Me2OH][BF4] resulted in the formation of the aminocarbene complex with an agostic α-C−H bond, trans-[MoF(CHNHBun)(dppe)2][BF4]. Analogous treatment of trans-[Mo(CNR)(L)(dppe)2] (R = Ph, Bun; L = p-MeOC6H4CN, CO (4)) with [Me2OH][BF4] gave aminocarbyne complexes trans-[Mo(⋮CNHR)(NCC6H4OMe-p)(dppe)2][BF4] and cis-[Mo(⋮CNHR)(CO)(dppe)2][BF4] (10). In solution at room temperature, the latter complexes gradually isomerized to the hydrido complexes [MoH(CNR)(CO)(dppe)2][BF4] (12). Related aminocarbyne complexes cis-[Mo(⋮CNMeR)(CO)(dppe)2][BF4] (13) were obtained from the reactions of 4 with [Me3O][BF4]. For comparison, carbonyl complexes trans-[Mo(CO)(N2)(dppe)2] and trans-[Mo(CO)(p-MeOC6H4CN)(dppe)2] were allowed to react with aqueous ...
