Monomeric Triorganotin(IV) Fluorides Containing a C,N-Chelating Ligand

The set of four triorganotin(IV) fluorides of general formula {2-[(CH3)2NCH2]C6H4}R2SnF, where R is Me (5), n-Bu (6), t-Bu (7), and Ph (8), respectively, has been prepared and characterized using NMR and ESI-MS techniques.

Description
Summary:The set of four triorganotin(IV) fluorides of general formula {2-[(CH3)2NCH2]C6H4}R2SnF, where R is Me (5), n-Bu (6), t-Bu (7), and Ph (8), respectively, has been prepared and characterized using NMR and ESI-MS techniques. The structures of crystalline compounds 5 and 8 were determined using X-ray methods. All compounds are monomeric both in solution using different solvents and in the solid state. The tin central atom is five-coordinated with all carbon atoms in equatorial positions and fluorine and nitrogen, from the intramolecularly coordinated dimethylamino group, in the axial positions of the distorted trigonal bipyramid. The ability of compounds 6 and 8 to perform fluorination of organometallic chlorides was tested on titanocene dichloride. A quantitative yield of Cp2TiF2 was obtained.
