Original language name

Solvent-Controlled Ring Size in Double C,N-Chelated Stannoxanes

Original language description

The stannylene (L-CN)(2)Sn where L-CN is a chelating ligand (2-(N,N-dimethylaminomethyl)phenyl-) was oxidized by an excess of oxygen, nitrous oxide, or TEMPO free radical, giving dimeric stannoxane [(L-CN)(2)Sn](2)(mu-O)(2) in dynamic equilibrium with its monomeric form in solution. In the solid state, an unusual tetraoxatetrastannacycle cyclo-[(L-CN)(2)SnO](4) can be crystallized from diethyl ether and the trioxatristannacyclic complex of formula cyclo-[(L-CN)(2)SnO](3) from the hexane solution. The same result has been obtained when C,N-chelated organotin(IV) dihalides ((L-CN)(2)SnX2, where X = Cl or Br) were hydrolyzed with an excess of sodium hydroxide and than dehydrated by azeotropic distillation. The oxobridged dihydroxide [(L-CN)(2)Sn(OH)(2)(mu-O) has been isolated during the course of this hydrolysis.
