MODELLKOMPLEXE DES NICKELS FUER DIE UMSETZUNG VON ALKINEN MIT KOHLENMONOXID: (PHENYLACETYLEN UND (bipy)Ni(CO)2)

Article abstract of DOI:10.1016/S0022-328X(00)89161-5

A five-coordinate, ligand-stabilised alkynenickel carbonyl complex (III), in which bond formation between carbon monoxide and the alkyne does not occur, is formed by reaction of (bipy)Ni(CO)2 (I) with phenylacetylene.The products (V and VII) from the reactions of III with carbon monoxide or t-butylisonitrile are described and characterised.A reaction scheme for the nickel-induced C-C-bond formation between alkynes and carbon monoxide is discussed.
