Abstract
A one-pot synthesis of 2,3,5-substituted 1H-pyrroles with yields of 37–77% by the reaction of terminal alkynes with aromatic and heteroaromatic nitriles in the presence of EtAlCl2 and the Cp2TiCl2 catalyst has been developed. Spectral-luminescent properties were studied and intense photoluminescence of 2,3,5-triphenyl-1H-pyrrole, 3-(2-phenylethyl)-2,5-diphenyl-1H-pyrrole, and 2,5-diphenyl-3-(pyridin-2-yl)-1H-pyrrole had been detected.
