Abstract

Complexes OsCl3{dbf(PiPr2)2} [1; dbf(PiPr2)2 = 4,6-bis(diisopropylphosphino) dibenzofuran], OsCl3{xant(PiPr2)2} [2; xant(PiPr2)2 = 9,9-dimethyl-4,5- bis(diisopropylphosphino)xanthene], and OsCl3{xant(PPh 2)2} [3; xant(PPh2)2 = 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene] have been obtained in high yield by the reaction of the corresponding diphosphine with OsCl 3·3H2O. The ruthenium(III) counterparts RuCl 3{dbf(PiPr2)2} (4), RuCl 3{xant(PiPr2)2} (5), and RuCl 3{xant(PPh2)2} (6) are similarly obtained from RuCl3·3H2O in moderate yields. The X-ray structures of dbf(PiPr2)2 and complexes 13 are also reported.
