Synthesis and chemical properties of [Z]-1-[2-(triaryl stannyl)vinyl]cyclooctanol

The compounds of [Z]-1-[2-(triphenyl stannyl) vinyl] cyclooctanol (1) and [Z]-1-[2-(tri-p-tolyl stannyl) vinyl] cyclooctanol (2) were synthesized by the reactions of triphenyltin hydride and tri-p-tolyltin hydride with 1-ethynyl cyclooctanol. The crystal structure of compound 1 was determined. The reactions of compound 1 and 2 with IC1, Br-2, I-2 formed nine organotin halides. The organotin oxide or hydroxide were prepared by the reactions of [Z]-1-[2-(phenyl dibromo stannyl) vinyl] cyclooctanol (6) and [Z]-1-[2-(diphenyl monobromo stannyl) vinyl] cyclooctanol (5) with KOH. Three complexes were obtained by the reactions of [Z]-1-[2-(phenyl diiodide stannyl) vinyl] cyclooctanol (8) with three ligands (2,2'-bipyridyl,5-nitro-1,10-phenanthroline,8-Hydroxyquinoline). The sixteen new compounds synthesized in this paper were characterized by means of elemental analysis, IR, H-1 NMR. The reaction mechanism of triphenyltin hydride and tri-p-tolyltin hydride with 1-ethynyl cyclooctanol were also proposed.
