6224-63-1, Tri-m-tolylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: A solution of N,N,N’-trisubstitutedacyl thiourea (0.564mmol) and phosphine ligand (0.564mmol) in a minimal amount of methanol, was added drop wise to a solution of K2PdCl4 (0.564mmol) in 40mL of methanol at 50?60¡ãC. The resulting mixture was stirred for 3?4 h and the precipitated complexes (1?8) (Scheme 1 ) were filtered, and washed with methanol. Single crystal X-ray diffraction measurement quality crystals were obtained by slow evaporation of chloroform/methanol (3:1) solution of the complexes. The 1H and 13C NMR, FT-IR, the elemental analyses, melting point data for the complexes (1?8) are as follows:(8) (Tri(m-tolyl)phosphine-kappaP)(1-(2-methylbenzoyl)-3-(N-methylphenyl)thioureido-kappa2(O, S)palladium(II) chloride Quantities used were 0.184?g (0.564?mmol) K2PdCl4, 0.161?g (0.564?mmol) 1-(2-methylbenzoyl)-3-(N-methylphenyl)thiourea, 0.172?g (0.564?mmol) tri(m-tolyl)phosphine in methanol.
