Abstract
Bridging methylcarbenc complexes [M2(CO)2-(µ-CO)(µ-CHMe)(η-C5H5)2](M = Fe or Ru) react with alkynes RC2′R1(R = R1= H, Me, CO2Me; R = Me, R1= H) under u.v. irradiation to produce complexes [M2(CO)(µ-CO)(µ-η1,η3-CRCR1CHMe)(η-C5H5)2], shown through an X-ray diffraction study of [Fe2(CO)(µ-CO)-{µ-η1,η3-C(CO2Me)C(CO2Me)CHMe}(η-C5H5)2] to arise from linking of the µ-carbene and alkyne.Keywords
