title: Preparation and structural characterization of trimethyltin(IV) tropolonate. Investigation of a rare methyl-migrational dismutation in the solution, solid and liquid states.
abstract: The synthesis and structural characterisation, by low temperature X-ray diffraction and solid-state NMR, of the highly reactive monomeric Me(3)Sn(trop) (1) complex has been studied; 1 rearranges into Me(2)Sn(trop)(2) (2) and Me(4)Sn by methyl-transfer dismutation. Based on the NMR kinetic data it appears that complex demethylates faster in the solid and liquid than in dilute CDCl(3) solution, but with a slower rate than in dilute CD(3)OD solution.
