文摘

The new water-soluble ligand dmPTA(OSO₂CF₃)₂ (1) (dmPTA = N,N'-dimethyl-1,3,5-triaza-7-phosphaadamantane)has been synthesized by reaction of PTA with MeOSO₂CF₃ in acetone (PTA = 1,3,5-triaza-7-phosphatricycle[3.3.1.1^3,7]decane). The reaction of 1 with KOH gave rise to the new water-soluble ligand dmoPTA (3) (dmoPTA= 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) by elimination of the -CH₂- group located betweenboth NCH₃ units. Compound dmPTA(BF₄)₂ (2) and complex [RuClCp(HdmoPTA)(PPh₃)](OSO₂CF₃) (4) have alsobeen synthesized, while compounds HdmoPTA(BF₄) (3a) and [RuClCp(dmPTA)(PPh₃)](OSO₂CF₃) (5) werecharacterized but not isolated. The new ligands and the complex have been fully characterized by NMR, IR, elementalanalysis, and X-ray crystal structure determination (ligand 1 and complex 4). The synthetic processes for 3 and 4were studied.
