  摘要：

  The ylide Ph2PCH=PPh2Me can be selectively P-alkylated by Mel or MeO3SCF3 to form the bis(methyldiphenylphosphonio)methylide salts [MePPh2CHPPh2Me]A (A=I (1), CF3SO3 (2)). The ylidic carbon shows a weak nucleophilicity and does not give typical reactions with common organic electrophiles, including Wittig type reactions, but it is able to displace tetrahydrothiophene in [AuX(tht)] to give the corresponding C-coordinated gold(I) compounds [Au{CH(PPh2Me)(2)}X]CF3SO3 (X=Cl (3), C6F5 (4)). The crystal structure of (4) displays a linear coordination for the gold atom, single P-C bond lengths and a PCP angle of 119.1(3)degrees for the ligand. (C) 2000 Elsevier Science Ltd.
