Cleavage of tin-aryl bond(s) by monohalocarboxylic acids : The steric factor role

All four tin-carbon bonds of tetra-p-tolyltin can be successively cleaved by iodoacetic acid. Reactions with tetra-m-tolyltin are sluggish and only one tin-carbon bond is cleaved, even in the presence of an excess of the acid. Tetra-o-tolyltin does not react under similar conditions. Steric factors are thought to be responsible for this difference in reactivity of tetratolyltins. The monocarboxylates were not isolated in case of Ph4Sn (except with CCl3COOH). Tetraphenylgermanium gives only the monocarboxylates Ph3GeOOCR′, (R′ = CH2Cl, CH2Br, CH2I), but all the Ph-Pb bonds in tetraphenyllead may be successively cleaved. Tri-p-tolyltin chloride reacts with iodoacetic acid to give a mixed chloro halocarboxylate, (p-MeC6H4)2SnCl(OOCCH2I), but attempts to prepare a mixed carboxylate by reacting (p-MeC6H4)3SnOOCCH2Cl with HOOCCH2I failed.

Triphenyltin trichloroacetate has been prepared by interaction of triphenyltinhydroxide with trichloroacetic acid in 2,2'-dimethoxypropane.Its acceptor property towards various -N, -O and -S donor Lewis bases has been studied and several new molecular adducts have been isolated and characterised.Physicochemical data suggest the presence of unidentate carboxyl group in the compounds.
