摘要：

The synthesis and properties of (Z)-17-[2-(triphenylstannyl)vinyl]-4-estren-17-ol (1) are described. Compound 1 crystallizes in the orthorhomblc space group P212121 (Z = 4) with a = 8.007 (2) Å, b = 15.152 (1) Å, and c = 26.807 (2) Å. 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 distorted-trigonal-bipyramidal geometry; as a consequence, a phenyl group, probably the apical one, is cleaved more easily by iodine than the vinyl substituent. © 1990, American Chemical Society.
