Ester elimination versus ligand exchange: the role of the solvent in tin–oxo cluster-building reactions
Abstract
Ester elimination between Sn(OBUt)4 and Sn(OAc)4 in refluxing toluene yields Sn6(O)6(OCMe3)6(O2CMe)6 which is characterized in solution and in the solid state by single-crystal X-ray diffraction; reaction of the same species in pyridine results in the formation of the ligand exchange products, Sn(OBut)X(OAc)4–x where x= 1–3.
