Fused hexacyclic tin compounds derived from 3-(3,5-di-t-butyl-2-hydroxy-phenylimino)-3H-phenoxazin-2-ol

The template synthesis of two tin compounds [N→Sn] 3-(2-oxo-phenylimino)-3H-phenoxazin-2-oxo-dimethyltin (1) and [N→Sn] 3-(2-oxo-phenylimino)-3H-phenoxazin-2-oxo-diphenyltin (2) is reported. The compounds are fused delocalized planar hexacyclic systems bearing a pentacoordinated diorganyl tin. They were identified by NMR, IR, TOF mass spectra and, for compound 1, by X-ray diffraction analysis.
