A novel route to methyleneamido ligands by protonation of nitriles ligating an electron-rich centre. Synthesis of trans-[ReCl(NCR)(dppe)2](R = alkyl or aryl, dppe = Ph2PCH2CH2PPh2) and [ReCl(N
CHC6H4OMe-4)(dppe)2][BF4]
Abstract
Treatment of trans-[ReCl(N2)(dppe)2](dppe = Ph2PCH2CH2PPh2) with NCR affords trans-[ReCl(NCR)(dppe)2](1; R = Me, C6H4Me-4, C6H4OMe-4, or C6H4F-4); (1, R = C6H4OMe-4) gives [ReCl(NCHR)(dppe)2][BF4] on treatment with HBF4.
