Phosphinoferrocene Amidosulfonates: Synthesis, Palladium Complexes, and Catalytic Use in Pd-Catalyzed Cyanation of Aryl Bromides in an Aqueous Reaction Medium
Original language description
The reaction of pentafluorophenyl 1'-(diphenylphosphino)ferrocene-1-carboxylate (4) with omega-aminosulfonic acids H2N(CH2)nSO3H (n = 1-3) in the presence of 4-(dimethylamino)pyridine and triethylamine affords the respective phosphinoferrocene amidosulfonates as crystalline triethylammonium salts, viz., (Et3NH)[Ph2PfcCONH(CH2)nSO3] (1, n = 1; 2, n = 2; 3, n = 3; fc = ferrocene-1,1'-diyl), in good yields. These ligands react smoothly with [PdCl2(cod)] (cod = eta(2):eta(2)-cycloocta-1,5-diene) to give theanionic square-planar bis-phosphine complexes trans-(Et3NH)2[PdCl2(Ph2PfcCONH(CH2)nSO3-kappa P)2] (5, n = 1; 6, n = 2; and 7, n = 3). The chloride-bridged dimer [LPdCl]2, where L is 2-[(dimethylamino-kappa N)methyl]phenyl-kappa C-1 auxiliary ligand, iscleaved with 1 to give (Et3NH)[LPd(Ph2PfcCONHCH2SO(3)-kappa P)] (8), in which the amidosulfonate coordinates as a simple phosphine. A similar reaction of [LPd(OAc)]2 and 1 proceeds under a partial elimination of (Et3NH)OAc to afford a mix
