Abstract

Ar₃SnX, where Ar = p-MeC₆H₄, p-CF₃C₆H₄ or Ph and X = OBu^t or NMe₂, are catalyst precursors for the ring-opening of lactides in benzene at 80 °C and the rate of ring-opening of lactides and a variety of related cyclic monomers is influenced by Ar and X such the chemistry of the ring-opening event and the initially formed product may be examined.
