Pri3)] (X = F, 6a; OPh, 6b). The molecular structures of 6a and 6b have been determined by X-ray crystallography. The reaction of the stibine complex [(η5-C5H5)Rh(CPh2)(SbPri3)], 2b, with PF3 proceeds by ligand displacement to afford the new carbenerhodium(I) compound [(η5-C5H5)Rh(CPh2)(PF3)], 7. The mechanism of the migratory insertion reaction is discussed.
所述carbenerhodium(我)络合物的反式- [的RhCl(器CPh 2)(L)2 ](L = PPR我3,图1A ; SbPr我3,图1b)与PF反应3由
铑的裂解卡宾键结合得到相应的PF 3衍
生物反式-[RhCl(PF 3)(L)2 ] 5a,b,产率很高。与此相反,治疗半夹心型化合物的[(η 5 -C 5 H ^ 5)的Rh(器CPh 2)(PPR我3)],图2a,与两个PF 3和P(OPH)3个通向洄游将CPh 2单元插入其中之一
环戊二烯基C-H键以形成所述环取代产物[η 5 -C 5 H ^ 4(CHPh配合2)}的Rh(PX 3)(PPR我3)](X = F,6A ; OPH,6B)。6a和6b的分子结构已通过X射线晶体学。的反应丁配合物[(η 5 -C 5 H ^ 5)的Rh(器CPh 2)(SbPr我3)],2B,与PF 3个前进通过
