Catalytic transformations of alkylthiophenes

The transformations of alkylthiophenes in the presence of amorphous aluminosilicate and decationated zeolite HNaY were studied. Substituted thiophenes with R = 2- and 3-Me, 2-Et, and 2-iso-Pr undergo dealkylation to thiophene with close rates, migration of the alkyl group from the 9α- to the β-position of the thiophene ring (or in the opposite direction with an elevated rate), and decomposition with H2S elimination. The dealkylation rate of 2-substituted thiophenes with a branched-chain radical (R = iso-Pr, terf-Bu) is much higher and the elimination rate with this radical is lower than those for normal-chain radicals; the isomerization step is virtually absent. Di-, tri-, and tetrasubstituted thiophenes with R = Et and iso-Pr undergo stepwise dealkylation, which is facilitated by an increase in the degree of substitution on the thiophene ring. Thiophene and its lower homologues can be obtained by the transformation of a mixture of high-molecular thiophenes. Copyright

INVESTIGATION OF THE MECHANISM OF THE RECYCLIZATION OF FURANS TO THIOPHENES AND SELENOPHENES UNDER ACID-CATALYSIS CONDITIONS. 3. INVESTIGATION OF THE RECYCLIZATION OF HOMOLOGS AND FUNCTIONAL DERIVATIVES OF FURAN. QUANTUM-CHEMICAL CALCULATIONS OF THE OBJECTS OF THE RECYCLIZATION

The kinetics of the conversion of di-, tri-, and tetraalkylfurans to the corresponding thiophenes were investigated.A correlation between the reactivities and structures of the investigated furans was established.Quantum-chemical calculations of the objects of the recyclization were made.The calculated and experimental data on the reactivities of the investigated compounds were compared.The most likely pathway of the protonation of furans in their recyclization was determined on the basis of calculations of the total energies of the protonated forms.
