The fragmentation mechanism on this component was discussed. The results showed the ring of raceanisodamine was crazed and characteristic ions m/z261 and base peak m/z94 were produced by losing free group CH2CH2OH, then its alcoholysis can create some ploy-ring ions such as m/z140 and m/z 156. These fragment act as the characters of raceanisodamine.展开更多
At room temperature, dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and 4 dimethylamine pyridine which affords the last products as binuclear copper?complex (1), [Cu(C6H5COO)2(C7H...At room temperature, dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and 4 dimethylamine pyridine which affords the last products as binuclear copper?complex (1), [Cu(C6H5COO)2(C7H10N2)]2. This complex is further characterized by spectroscopic methods. The structure of complex (1) has been determined by a single crystal X ray analysis. Crystallographic data are as follows: monoclinic, space group P21/n, a=10.446(2)?, b=11.140(5)?, c=17.179(3)?, β=95.92(3)°, V=1988.4(7)?3, Z=4, F(000)=884, μ=11.27cm-1, D(calcd.)=1.429g·cm-3, R=0.0399, Rw=0.1202. Each copper?ion is coordinated by two bridging bidentate benzoate and 4 dimethylamine pyridine to form dimeric molecule. CCDC: 188744.展开更多
