SYNTHESIS OF (P-TOLSB)(N) BY REACTION OF CP(2)CO WITH P-TOLSBCL(2), CRYSTAL STRUCTURE OF [CP(2)CO][P-TOLSBCL(3)], AND ELECTROREDUCTION OF P-TOLSBCL(2)

摘要

The reaction of Cp(2)Co with p-TolSbCl(2) in THF gives (p-TolSb)(n) and [Cp(2)Co][p-TolSbCl(3)]. H-1 NMR experiments show that this method is also useful for the syntheses of the rings (ArSb)(n) (Ar = Ph, o-Tol, m-Tol, p-Tol). The structure of [Cp(2)Co][p-TolSbCl(3)] has been determined by single crystal X-ray diffraction. It contains a centrosymmetric double chlorine-bridged dimeric anion. The two-electron reduction of p-TolSbCl(2) gives (p-TolSb)(n). [References: 14]
