The alkenethiones, mentioned in the title, react with sodium N-chlorobenzenesulfonamides (2) to S-alkenylidene-N-arylsulfonylsulfimides (6, 9). Cyclohexenylidenesulfimides 6 are oxidized to dipolar N-(arylsulfonyl)iminioalkenesulfonamidates (7). Equilibri

-
Experimental evidence has been obtained indicating the existence of a neutral intermediate with tetrahedral structure in the aminolysis of 2-alkoxy- and 3-alkylthio-2-cyclohexene-1-thiones.

- α,β-UNSATURATED THIO COMPOUNDS. XIII.* HYDROTHIOLYSIS OF β-HETERO-SUBSTITUTED α,β-UNSATURATED IMMONIUM SALTS AT THE C=N(+) BOND - A GENERAL APPROACH TO THE SYNTHESIS OF FUNCTIONALLY SUBSTITUTED THIOKETONES
-
The hydrothiolysis of immonium salts containing the Y-C=C-C=N(+) group takes place at the C=N(+) bond and not at the C-Y bond.This is consistent with the results from quantum-chemical calculations.On this basis a general approach was formulated to the synthesis of new types of organic sulfur compounds, i.e. β-alkoxy-, β-alkylthio-, and β-halogen-substituted α,β-unsaturated thioketones of the Y-C=C-C=S (Y=RO, RS, Hlg) type.
