摘要：

The reaction of [Ru-2(O2CCF3)(2)(mu-O2CCF3)(2)(COD)(2)(mu-H2O)] with 1,1'-diphenyl-3,4,4'-tetramethyl-2,2'-biphosphole (I) provides trans-meso-[Ru(trifluoroacetate)(2)(1,1'-diphenyl-3,3',4,4'-tetramethyl-2;2'- biphosphole)(2)] complex 3, which spontaneously isomerizes in solution into cis-(+/-)-[Ru(trifluoroacetate)(2)(1,1'-diphenyl-3,3',4,4'-tetramethyl-2,2'-biphosphole)(2)] complex 4. These new bis-biphosphole-ruthenium complexes have been characterized by X-ray diffraction.
