  立体不稳定铁（II）d6-MD5酰基中间体的DNMR表征

  摘要：

  Solutions of fac-[(diars)Fe(CO)3Me]+ (fac-7; diars = o-phenylenebis(dimethylarsine)) in acetonitrile (AN) rapidly form an equilibrium mixture containing unreacted fac-7 as well as the two isomeric acyl complexes cis,cis-[(diars)Fe(CO)2(C(O)Me)(AN)]+ (9a) and cis,trans-[(diars)Fe(CO)2(C(O)Me)(AN)]+ (9b). Acyls 9a and 9b interconvert by an intramolecular dissociative process which is fast on the NMR time scale above ambient temperature. DNMR evidence is consistent with the formation of a stereochemically nonrigid pentacoordinate (MD5) eta-1-acyl intermediate which generates a time-average symmetry plane orthogonal to the diars o-C6H4 ring. Under identical conditions mer-[(diars)Fe(CO)3Me]+ (mer-7) gives only cis,-cis-[(diars)Fe(CO)2(C(O)Me)(AN)]+ (9c), which forms 9a and 9b in a slow, irreversible reaction.
