Water-soluble 3.,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (dmoPTA) as a polydentate ligand: Synthesis of [RuClCp(PPh3)-mu-dmoPTA-1 kappa P : 2 kappa N-2,N'-Co(acac-kappa O-2,O')2]center dot H2O
The dinuclear complex [RuClCp(PPh3)-mu-dmoPTA-1 kappa P:2 kappa N-2,N'-Co(acac-kappa O-2,O')(2)]center dot H2O (2;dmoPTA = 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) has been synthesized by reaction of [RuClCp(HdmoPTA)(PPh3)](OSO2CF3) (1) with Co(acac)(2) in methanol (HdmoPTA = 3,7-H-3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane). Elemental analysis, IR, NMR, and single-crystal X-ray structure determination have characterized the new complex. This complex is active for the catalytic isomerization of but-1-en-3-ol in acetone better than 1.
