摘要:
Reaction of (Me(3)P)(3)RhCl with (THF)(3)LiSi-(SiMe(3))(3) in the presence of 2-butyne or diphenylacetylene generates (Me(3)P)(2)(Me(3)Si)RhSiMe(2)C(R)=C(R)SiMe(SiMe(3)) (1, R = Me; 2, R = Ph). These complexes undergo a fluxional process which exchanges the SiMe(3) groups, apparently by Si-Si bond reductive elimination/oxidative addition.
