Novel α,β-C,C-Coupling Reaction of 1-Alkynyl Groups via I2 Oxidation at Nickelate(II) Centers
摘要:
C,C-coupling of RC=C- ligands (R=Me3C, Me3Si) coordinated to Nast-type nickelate centers is initiated by It and regioselectively steered by trimethylphosphine to afford the (1-(trimethylphosphonio)-sigma-vinyl)nickel complexes Nil(2)[(CPMe3)=C(C=CR)R]PMe3.
