Reactions of Diphenyltin¹

Abstract

The reactions of diphenyltin with the following reagents have been examined: hydrogen peroxide, chlorine, bromine, iodine, sulfur, benzoquinone, benzoyl peroxide, dibenzyl disulfide, stannic chloride, mercuric chloride, diphenyltin dichloride. Diphenyltin forms a complex with boron trifluoride which disproportionates in boiling benzene to tetraphenyltin and metallic tin. Nitrobenzene and benzil catalyze the polymerization of diphenyltin.

Lattice dynamic anisotropy in diphenyl tinoxide and diphenyl tinquinone polymers

“…Since < u 2 > and 12/11 are strongly influenced by changes in intermolecular bonding (2,3), the analysis of the Mossbauer line shape can lead to important conclusions concerning the lattice anisotropy in polymers (4,5). W e selected diphenyltinoxide (6-8) and diphenyltinquinone (9) to study the differences in molecular motion between strong pseudoionic Sn-0-Sn and SnOC6H40-Sn linkages. It h a s been speculated that both high polymers have a CdI2 layer structure with anion vacancies and i t is thought that the tin atom h a s presumably five next-nearest neighbors, where the fifth ligand is an oxygen from a neighboring chain.…”
