✦ Synopsis

The first rotational isomers of thiobenzaldehydes, TbtCH=S (2a and 2b: Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl), were synthesized and isolated as stable crystalline compounds by the desulfurization of the corresponding overcrowded cyclic polysulfides TbtCHS, (n = 5 or 8) with phosphine reagents. The molecular structures of 2a and 2 b in the solid state, determined by X-ray crystallographic analysis, differed in their confor-mations, which were essentially identical with those in solution as revealed by 'H('H} nuclear Overhaus,er effect (NOE) experiments.
