二丁基二氯化锡与全氟丁基磺酸银在丙酮中室温反应,得到二丁基二全氟丁基磺酸锡.该配合物在空气中放置2d,1HNMR表明其结构未发生变化,TG.DSC表明在220℃是稳定的;配合物C4F9S03)2SnBu2能溶解在乙酸乙酯、丙酮、乙腈、四氢呋喃、乙醚等极性有机溶剂中,但室温下,在非极性溶剂己烷、二氯甲烷、甲苯中不溶.以乙腈作溶剂,室温下,(C4F9S03)2SnBu2的用量分别为1.0和5.0m01%,醛的烯丙基化反应和Mukaiyama—aldol反应有效进行,高产率得到对应产物.
Bisperfluorobutylsulfonate bisbutyltin complex was successfully synthesized by treating C4F9SO3Ag with Bu2SnC12 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, CHEC12, toluene at room temperature. In the presence of 1.0 and 5.0 tool% of bisperfluorobutylsulfonate bisbutyltin respectively, allylation of aldehyde and Mukaiyama ald01 reaction could efficiently occur in CHaCN at room temperature and give high yield of the cor- responding products.
