Abstract

Abstract (Me3P)2Ni(C2H4) (5) and (dmpe) 2Ni2(C2H4)3 (6) react with various alkynes including ethyne (acetylene) and 1-alkynes to form the crystalline compounds (Me3P)2Ni(C2RR′), (dmpe)Ni(C2RR′), and (dmpe)2Ni2(C2R2)2 (R.R′ = H, Me, Ph). Structural assignments were made on the basis of 1H, 13C, and 31P NMR data. The crystal and molecular structure of (dmpe)Ni(C2Ph2) (17) has been determined by X-ray crystallography.
