Sulphides organotin—

XXXVIII Organotin sulphides, selenides, and tellurides (containing an Sn-X-Sn bond). [Pg.320]

The base strength measurements suggest that the organotin sulphides such as (CH3)3SnSSnfCH3)3 are stronger bases than the simple organic sulphides. This would be in accord with little or no back-bonding from sulphur to tin, and tin s lower electro-... [Pg.78]

CF3)2PSP(CF3)2 and Me3SiCl. Conformational isomerism in cyclotrisil-thianes has been studied by n.m.r. Tetra(methylgermanium) hexa-sulphide has been shown by A -ray crystallography to possess an adamantane-t) structure (Figure 19). The mean Ge—C and Ge—S bond distances are 1.922 A and 2.218 A, respectively. Vibrational spectra for organotin thiolates and sulphides - and for the compounds M(SR)4 (M = Si, Ge, or Sn) have been reported. [Pg.371]

The cyclic organotin selenide (Me2SnSe)3 adopts a twist-boat conformer similar to the sulphide, with the tin tetrahedra only slightly distorted. The tellurium derivative can be prepared in good yield directly from the element, using MeaSnHa. ... [Pg.164]
