【Abstract】 An organotin compound, [n-Bu2Sn(OH)OS(O)2( p-ClPh)]2, has been synthesized by the reaction of n-Bu2SnO with p-ClPhSO3H and characterized by IR, elemental analysis and X-ray diffraction single crystal structure analysis. The results show that it possesses a polymeric sheet structure with repeating 20-membered macrocycles by virtue of the bridging bidentate sulfonate groups; the crystal belongs to monoclinic, space group P21/c with a=1.460 72(12) nm, b=0.897 41 (11) nm, c=2.896 94 (14) nm, β=107.629 (4)°, V=3.619 2 (6) nm-3, Z=4; all the tin atoms are sixcoordinated in a distorted octahedral geometry. The compound showed the very high catalytic activity in the transesterification of dimethyl carbonate and phenol to diphenyl carbonate. CCDC: 751163.更多还原
