Bisperfluorobutylsulfonate bisbutyltin complex was successfully synthesized by treating C4F9SO3Ag with Bu2SnCl2 in acetone at room temperature. When the complex was exposed to air two days, 1H NMR spectra showed that its structure had no change. TG-DSC showed that the complex was stable below 220 ℃. The complex had a good solubility in polar solvents, such as ethyl acetate, acetone, acetonitrile, THF, ethyl ether. But it was poor soluble in hexane, CH2Cl2, toluene at room temperature. In the presence of 1.0 and 5.0 mol% of bisperfluorobutylsulfonate bisbutyltin respectively, allylation of aldehyde and Mukaiyama aldol reaction could efficiently occur in CH3CN at room temperature and give high yield of the corresponding products.

Key words: bisperfluorobutylsulfonate bisbutyltin, allylation of aldehyde, mukaiyama-aldol reaction
