Abstract: (Z)-1-Triphenylstannyl-3-p-chlorophenyl-1-butene-3-ol(1) was synthesized by the additive reaction of 3-p-chlorophenyl-1-butyne-3-ol with triphenyltin hydride. The phenyl groups in compound 1 were substituted by ICl, Br2 or I2 to yield mono- and dihalide derivatives(2—8). Compounds 1—8 were characterized by elemental analysis, 1H NMR and FTIR spectroscopy. The crystal structures of compounds 1, 3 and 5 were determined by single crystal X-ray diffraction analysis. Sn atom in compound 1 exhibits a distorted tetrahedral structure due to a weak intramolecular interaction between Sn and the hydroxyl O atoms (0.281 and 0.283 nm), while the Sn atom in 3 and 5 adopts a trigonal bipyramidal geometry with a significant Sn1←O interaction [0.240 1(6) nm in 3 and 0.238 4(7) nm in 5]. The Lewis acidities of the Sn atoms are in the following order: PhSnX2>Ph2SnX>Ph3Sn.
