| Abstract: | A new dibenzyltin phenylsulfonate,(PhCH 2) 2 Sn(OS(O) 2 Ph) 2(H 2 O) 2,has been synthesized by the reaction of (PhCH 2) 3 Sn] 2 O with PhSO 3 H,and characterized by infrared spectrum,elemental analysis and X-ray diffraction single crystal structure analysis.The complex belongs to monoclinic,space group P2 1 /c with a=1.458 71(8) nm,b=1.178 21(8) nm,c=0.758 18(4) nm,β=92.393(2)°,V=1.301 92(13) nm-3,Z=2.In the complex,each tin atom is six-coordinated with a slightly distorted octahedral geometry.When(PhCH 2) 2 Sn(OS(O) 2 Ph) 2(H 2 O) 2 catalyzed the transesterification of dimethyl carbonate and phenol to synthesize diphenyl carbonate,the conversion of dimethyl carbonate was up to 55.8% with a close 100% transesterification selectivity. |
| Keywords: | dibenzyltin phenylsulfonate transesterification dimethyl carbonate diphenyl carbonate |
