An S-oxide of 6-tert-butyl-6-phenylpentathiane. Structure in the crystalline state and in solution and thermal decomposition

Oxidation of 6-tert-butyl-6-phenylpentathiane with trifluoroperacetic acid gave the pentathiane 3-oxide mainly as the monooxide. The 3-oxide takes a twist conformation both in the crystalline state and in solution. Thermal decomposition of the 3-oxide in the presence of 2,3-dimethyl-1,3-butadiene yielded both S2O- and S2-transferred products.

The synthesis of the six membered heterocycles (1) and (2) are described.Thermolysis of 1 generates the germylated heterocycles (3), (4), (5) and (AnPS2)3,4.These results are explained by a mechanism involving expulsion of and decomposition of the resulting transient thiadigermetane with formation of and .Exchange reactions between 1 and various chlorides are described.With metal 14 chlorides Σ2MCl2 the reactions lead to transient and metallathiones ; while with SCl2 the reaction leads to and singlet sulfur . - Key words: Germylated and phosphorylated heterocycles, transient species, germathione, singlet sulfur.
