The reactions of the very bulky phosphine ligands containing both tert-butyl and ortho- trifluoromethylphenyl substituents with [PdCl2 (PhCN) 2] have been studied, in order to assess the impact of steric and electronic effects on a ligand's coordination ability. The palladium complexes of tert-butyl (ortho-trifluoromethylphenyl) methyl phosphine and tert- butyl (ortho-trifluoromethylphenyl)(n-butyl) phosphine were characterised by X-ray ...
