1,2-Dithienylethanediones were synthesized by modified acylation of thiophene and its homologs in the presence of aluminum chloride and pyridine. The bishydrazones of the products were converted into dithienylacetylenes by oxidation with atmospheric

The interaction of 2,4-disubstituted thiophenes with AlCl3 and CCl4 or tert-BuCl proceeds through cationic σ-complexes corresponding to electrophilic substitution; the deprotonation of these complexes to form 2,3,5-trisubstituted products is sterica

A new route for the synthesis of 2,4,5,6-tetrachloroisophthalic and 2,3,5,6-tetrachloroterephthalic aldehydes from the corresponding tetrachlorobenzenes was developed. The method involves dichloromethylation of the initial compounds with chloroform i

The disproportionation products of the C-protonation of 5-tert-butyl-2-methyl- and 2-ethylthiophene first give 4-tert-butyl-2-methyl- and 2-ethylthiophene. We studied the electrophilic trichloromethylation of a series of 2,4-dialkyl thiophenes and sh
