elemental anal. were determine These results showed that the structure of these compounds consists of discrete mols. containing four-coordinate tin atoms. Possible steric hindrance of the bulky cyclohexyl groups prevents close approach of a second carboxyl group. The effect of positions of substituents in aromatic carboxylates on reaction yields are also discussed.
