  摘要：

  Treatment of N-tosyl aziridine with KPPh2 in THF produces Ph2PCH2CH2NTsK (Ts = p-CH3C6H4SO2). Reaction of Ph2PCH2-CH2NTsK with [Rh-2(mu(2)-Cl)(2)(NBD)(2)] (NBD = norbornadiene) and [Rh-2(mu(2)-Cl)(2)(COD)(2)] (COD = 1,5-cyclooctadiene) produces [Rh(NBD)(Ph2PCH2CH2NTs)] and [Rh(COD)(Ph2PCH2CH2NTs)] (4), respectively. Reaction of Ph2PCH2CH2NTsK with [Ir-2(mu(2)-Cl)(2)-(COD)(2)] gives [Ir(COD)(Ph2PCH2CH2NTs)]. Complex 4 is catalytically active for polymerization of arylalkynes and for cyclotrimerization of HC=CCOR (R = OEt, Me). The novel metallacycle [Rh(C(CO2Et)=CHC(CO2Et)=CH)(CH(CO2Et)=CC-=CCO2Et)(Ph2PCH2CH2NHTs)(2)] was isolated from the reaction of 4 with ethyl propiolate. The metallacycle is catalytically active for cyclotrimerization of ethyl propiolate. (c) 2006 Elsevier B.V. All rights reserved.
