摘要：

The inner-sphere triflate complex [(C5Me5)-Ir(eta3-C3H5)OTf] (5), formed quantitatively on photolysis of [(C5Me5)Ir(eta3-C3H5)(eta2-C3H6)]+OTf-, reacts with di-substituted alkynes to form the highly reactive allyl alkyne complexes [(C5Me5)Ir(eta3-C3H5)(RC=CR)]+OTf-(3), in accessible by conventional methodology. Although the allyl alkyne complexes undergo facile reductive ligand coupling to form the substituted bis(cyclopentadienyl) complexes 2, these complexes can be isolated and converted selectively to the metallacyclobutane alkyne complexes 6 in high yield by reaction with nucleophiles.
