1,3-Disubstituted tetrakis(fluoroalkyl)distannoxanes (XRf2SnOSnRf2Y)2 (Rf=C6F13C2H4, C4F9C2H4; X, Y=Cl, Br, NCS) were synthesized from readily available dibenzyltin dibromide. The dimeric formulation of these compounds that was confirmed by 119Sn-NMR spectra gave rise to a structure in which the metalloxane core is covered by the surface fluorophilic alkyl groups. Thus, these compounds exhibited high solubility in fluorocarbon solvents and large partition coefficients for FC-72 against common organic solvent.

A variety of organotin triflate clusters are obtained by treating dialkyltin oxide with triflic acid (TfOH) in different ratios. When R2SnO is exposed to 0.5 equivalents of TfOH, 3-hydroxy-1-triflato distannoxanes (1) are formed which have a novel sheet-like structure in the solid state. Treatment of R2SnO with 2:3 or one equivalent of TfOH affords a trinuclear cluster 3 or cationic dimers 2. The stoichiometry of the novel trinuclear cluster can be confirmed by various chemical reactions as well as elemental analysis. On the basis of 119Sn-NMR study, the equilibrium has been revealed between 2 and 3. The use of two equivalents of TfOH in the reaction with R2SnO offers a convenient route for R2Sn(OTf)2 (4).

采用氟碳2有机溶剂两相催化体系，考察了1，1，3，3-四（全氟己基乙基）二锡氧烷二聚体（1）在环氧化合物开环反应中的催化作用。结果表明，催化剂（1）在氟碳2有机溶剂两相体系中使环氧苯乙烯和甲醇的开环反应产率高达95%，13C NMR谱表明，开环反应的区域选择性为100%。在氟碳2有机溶剂两相催化体系中以一锅法制备了3-苯基丙酸2-甲氧基-2-苯乙醇酯，收率高，方法简便，催化剂几乎可以定量回收循环使用。
