文摘

The reaction of 1 with 1,1-bis(diphenylphosphino)ethene (vdpp) gave the mononuclear cyclometalated compound 2. The withdrawing effect of the cyclopalladated moiety suffices to polarize the C=CH₂ doublebond to afford the addition products 3-8, by treatmentof complex 2 with primary aliphatic and aromaticamines. The molecular structures of 2, 4, and 8 havebeen determined by X-ray crystallography, showing thatthe C-C distance in 4 and 8 has the expected single-bond length upon addition.
