Abstract
The compounds (C6F5)nPh3–n X (X = P, As, or Sb; n= 1, 2, or 3) have been prepared in high yield by an improved method using pentafluorophenyl-lithium. The reactions of these ligands with various rhodium, palladium, and platinum compounds have been investigated and displacement reactions indicate that the complexes L2PtCl2 increase in stability in the order of ligands (L), Me2S < (C6F5)3P < (C6F5)Ph2As < (C6F5)2PhP < tris(2,6-di-fluorophenyl)phosphine < cyclo-octa-1,5-diene < Ph3As < (C6F5)Ph2P < Ph3P < (PhO)3P. The i.r. spectra (400–200 cm.–1) and 19F n.m.r. spectra of the compounds are reported.Keywords
