Abstract
1,3-Disubstituted tetrakis(fluoroalkyl)distannoxanes (XRf 2SnOSnRf 2Y) 2 (Rf=C 6F 13C 2H 4, C 4F 9C 2H 4; 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.
