Abstract
The new palladium complexes with NHC and phosphine ligands, cis-PdCl2(L2)(PPh3) (2), cis-PdBr2(L2)(PPh3) (3), and cis-PdCl2(L3)(PPh3) (4) were prepared following a general protocol of a one pot reaction between PdCl2(COD), PPh3, and the ligand precursors LH·Y (Y = Cl, Br, BF4) (L2 = 1,3-dibenzylimidazolin-2-ylidene; L3 = 1,3-dibenzylimidazol-2-ylidene). The cis-PdCl2(L3)(PCy3) complex (5) was prepared by the ligand substitution reaction between 4 and PCy3. The palladium complexes with NHC and pyridine complexes, trans-PdCl2(L)(py) (6: L = L2; 7: L = L3) were obtained by heating a mixture of PdCl2(COD) and LH·BF4 in pyridine. A similar reaction condition using CH3CN as solvent with KOtBu as base afforded cis-PdCl2(L3)2 (8). Complexes 2−8 were successfully characterized by X-ray crystallographic studies, among which, intriguingly, two polymorphs of 8 were obtained. Thermogravimetric analysis showed that the cis-PdX2(NHC)(PR3) complexes are more thermally stable than the trans-PdCl2(NHC)(py) complexes. Toget...
