Series of bisamidinato and bisguanidinato tin(IV) diolates prepared from 1,2-diones (3,5-di-tert-butyl-o-benzoquinone, 3,4,5,6-tetrachloro-1,2-benzoquinone, 9,10-phenanthrenedione, acenaphthenequinone, 1,2-diphenylethanedione) and {Cy-NC(n-Bu)N-Cy}(2)Sn or {pTol-NC[N(SiMe3)(2)]N-pTol}(2)Sn, respectively, were used as efficient initiators for ring-opening polymerization of epsilon-caprolactone. Moderate to good efficiency of selected compounds in trimethylene carbonate polymerization was also observed.
