Phosphine-free palladium catalytic system for the selective direct arylation of furans or thiophenes bearing alkenes and inhibition of heck-type reaction

Palladium acetate associated to potassium carbonate as catalytic system has been found to efficiently catalyse the direct 5-arylation of furans or thiophenes bearing enal, enone or acrylate functions at carbon C-2, and to inhibit the Heck-type reaction. The nature of the base is crucial to control the selectivity of the arylation. In the presence of electron-deficient aryl bromides and potassium carbonate as the base, the direct arylation is favoured, whereas the use of potassium fluoride gave selectively the Heck-type product, and tri-n-butylamine the reductive addition product.

Synthesis and Absorption Spectral Properties of Substituted Phenylfurylbenzothiazoles and their Vinylogues

A number of substituted 2-(5-aryl-2-furyl)benzothiazoles and their vinylogues were synthesized from corresponding 5-arylfurfurals by convenient methods.The yields of products and their UV/Vis spectroscopic properties are substituent-dependent. - Keywords. 2-(5-Aryl-2-furyl)benzothiazoles; 1-(5-Aryl-2-furyl)-2-(2-benzothiazolyl)ethenes; Absorption spectra.

ARYLATION OF FURAN COMPOUNDS BY ARENEDIAZONIUM SALTS

3-(5-Aryl-2-furyl)acrylic acids were obtained by the reaction of 5-arylfurfurals with malonic acid.They were arylated by diazonium salts with decarboxylation and the formation of 5-aryl-2-styrylfurans.The latter were also obtained by the interaction of furylacrolein with diazonium salts.This reaction also gave 3-(5-aryl-2-furyl)acroleins and the corresponding arylfurylacrylic acids, which were arylated again with the release of CO2 and the formation of 5-aryl-2-styrylfurans. 3-(5-Aryl-2-furyl)acroleins were also synthesized by the condensation of 5-arylfurfurals with acetaldehyde under phase-transfer conditions.The s-trans configuration of the furan ring and the exocyclic double bond were established in the obtained compounds by the PMR method.
