## Abstract In the reaction of pyrroles with tetrahaloโ1,4โbenzoquinones two different processes occur: the oxidation of pyrrole and the coupling reaction to 3,5,6โtrihaloโ2โ(pyrrolโ2โyl)โ1,4โbenzoquinones. Excess of pyrrole results in doped polypyrrole as the principal reaction product. Excess of
## Abstract Anions of enolized heteroaromatic 1,3โdicarbonyl systems, such as the title compounds **1, 9,14**, and **19**, react in dimethylformamide in the presence of potassium carbonate with diaryl disulfides **2** to yield arylsulfenyl derivatives (**3, 10, 15, 20**). The arylthiolate anions **
In the title compound, C 15 H 18 N 2 O 4 S, the packing is consolidated by an intra/intermolecular bifurcated O-Hร ร ร(O,O) and intermolecular N-Hร ร รS hydrogen bonds. The tetrahydropyrimidin-2-one ring is twisted. ## Related literature For background, see: Kappe (1993). ## Experimental Cryst
The title compound, C 14 H 16 N 2 O 4 S, was synthesized by the reaction of 4-hydroxy-3-methoxybenzaldehyde, thiourea and methyl 3-oxobutanoate in ethanol under reflux. The crystal structure is stabilized mainly through intermolecular N-Hร ร รS and O-Hร ร รO hydrogen bonds. The tetrahydropyrimidin-2
