(Z)‐1‐[2‐(Tribenzylstannyl)vinyl]‐1‐cyclooctanol: Synthesis, Characterization, Halodebenzylation, and Crystal Structure

Abstract

The synthesis and properties of (Z)‐1‐[2‐(tribenzylstannyl)vinyl]‐1‐cyclooctanol (1) are described. Compound (1) crystallizes from alcohol in the monoclinic space group P2 ₁ /c with unit‐cell dimensions a = 9.348(1) Å, b = 26.143(1) Å, c = 10.705(1) Å, β = 95.09(1)°, V = 2605.9(1) Å³, Z = 4, D _c = 1.390 g cm⁻³, μ = 10 cm⁻¹, final R = 0.033 for 3165 observed reflection (|F|² ≥ 8σ|F|²). The x‐ray diffraction analysis of this compound shows intramolecular coordination of oxygen to the tin atom giving rise to a five‐membered ring in which the metal exhibits a distorted trigonal bipyramidal geometry. Compound (1) by halodebenzylation by Br₂ or ICl forms the corresponding (Z)‐1‐[2‐(dibenzylhalostannyl)vinyl]‐1‐cyclooctanol or (Z)‐1‐[2‐(benzyldi‐halostannyl)vinyl]‐1‐cyclooctanol, respectively. All compounds were characterized by elemental analyses, IR, ¹H NMR.
