Abstract

The syntheses of two new phosphine–thiophene ligands, 2-(2′-{diphenylphosphino} phenyl) thiophene (dpppth) and 3′-diphenylphosphino-2, 2′∶ 5′, 2′′-terthiophene (dppterth) are reported. These ligands react with [RuCl2 (PPh3) 3] to give [RuCl2 (dpppth-P, S) 2] and [RuCl2 (dppterth-P, S1) 2], respectively, which both exist as a mixture of two isomers in solution.[RuCl2 (dpppth-P, S) 2] reacts at 25° C with carbon monoxide to yield ...
