Abstract

A series of novel tin(IV)-heteroaryl alkenolates of the general formula [Sn(DMOTFP)(2)X-2] (3-6, X = F, Cl, Br, I) were prepared by direct oxidative halogenation of the corresponding tin(II) derivative [Sn-II(DMOTFP)(2)] (2) and by cleavage of the carbon-tin bonds in diphenyltin dichloride [Ph2SnCl2] by (4,5-dimethyloxazolyl)-1,1,1-trifluoropropen-2-ol, (H-DMOTFP, 1) with a subsequent halide exchange reaction. The molecular structures elucidated in solution (multi-nuclear NMR spectroscopy) and by single crystal X-ray diffraction confirmed the sixfold coordination of the tin(IV) center with a distorted octahedral arrangement of ligands. An unusual centrosymmetric octahedral trans-dihalo configuration was found for the compounds [Sn-IV(DMOTFP)(2)X-2] (X = Cl, Br, I), while the compound [Sn(DMOTFP)(2)F-2] adopted a cis-dihalide configuration.
