摘要：
The synthesis and properties of (Z)-1-(triphenylstannyl)-3-phenyl-1-buten-3-ol (1) are described. Compound 1 crystallizes from alcohol in the monoclinic space group P21/c with unit-cell dimensions a=9.296(2), 6=14.081(3), c=18.390(5) A,B=97.70(2), V=2385.5(1) A3, Z=4, F(000)=1008, Dc=1.38 g.cm-3,u=10.88 cm-1, final R=0.0359 for 3079 observed reflection [I > 3(I)]. The X-ray diffraction analysis of this compound shows the presence of an intramolecular coordination to the tin atom giving rise to a five-membered ring in which the metal exhibits a distroted trignoal bipyramidal geometry; as a consequence, a phenyl group, probably the apical one, is cleaved more easily by bromine than the vinyl substituent.
