摘要
Complexes OsCl3{dbf((PPr2)-Pr-i)(2)} [1; dbf((PPr2)-Pr-i)(2) = 4,6-bis(diisopropylphosphino)dibenzofuran], OsCl3{xant((PPr2)-Pr-i)(2)} [2; xant((PPr2)-Pr-i)(2) = 9,9-dimethyl-4,5-bis(diisopropylphosphino)xanthene], and OsCl3{xant-(PPh2)(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 OsCl3 center dot 3H(2)O. The ruthenium(III) counterparts RuCl3{dbf((PPr2)-Pr-i)(2)} (4), RuCl3{xant((PPr2)-Pr-i)(2)} (5), and RuCl3{xant(PPh2)(2)} (6) are similarly obtained. from RuCl3 center dot 3H(2)O in moderate yields. The X-ray structures of dbf((PPr2)-Pr-i)(2) and complexes 1-3 are also reported.
