Abstract

Abstract Di-organotin(IV)halides R 2SnCl 2 (R=Me or Ph) react with bis(diphenylphosphine)methane (DPPM) and bis(diphenylphosphine)ethane (DPPE) in ethanol in aerobic conditions yielding 1:1 adducts [R 2SnCl 2(DPPM–O 2)] and [R 2SnCl 2(DPPE–O 2)], respectively, containing the bis(diphenylphosphine) in oxidized form. The 1:1 adduct [SnMe 2Cl 2(DPPM–O 2)] is composed of separate molecules containing six-coordinate tin, with the ligands coordinated in the bidentate O 2-fashion, whereas [SnMe 2Cl 2(DPPE–O 2)] is polymeric, with octahedral and centrosymmetric (all trans) tin atoms. In inert atmosphere, the interaction between R 2SnCl 2 and DPPM or DPPE does not take place. Mono-organotin halides RSnCl 3 (R=Me, Bu n or Ph) react with DPPM and DPPE yielding 1:1 adducts [RSnCl 3(DPPM)] (R=Me, Bu n or Ph) and [RSnCl 3(DPPE)] (R=Bu n or Ph).
