Abstract
Hexaethyldistannoxane and its chloro derivatives when treated with lactones containing four- to seven-membered rings afforded 11 adducts with opening of the rings. Kinetic measurements utilizing IR spectroscopic methods gave the following orders of reactivity: (1) ϵ-caprolactone > δ-valerolactone >β-propiolactone > γ-butyrolactone, (2) Cl2EtSnOSnEt2Cl > Et3SnOSnEt3 > ClEt2SnOSnEt3 > ClEt2SnOSnEt2Cl; monomeric > dimeric distannoxane, and in non-polar solvent > in polar or basic solvent. These results are discussed in terms of the degree of association of distannoxanes, as well as the acidities and basicities of the lactone, distannoxane and solvent.
