Abstract

Abstract The triphenylphosphane derivatives 2a and 5, bearing one and two phosphonic ester groups, are accessible in high yields by consecutive Pd-catalyzed P–C coupling reactions of p-bromoiodobenzene with Ph 2 PH and PhPH 2, respectively, and then with diethyl phosphite. Ester hydrolysis yields the highly water-soluble sodium salts of mono-and bis-phosphonated triphenylphosphane, 3a and 6, respectively. On reaction of the p-and m ...
