An Fe/S catalyst generatedin situfrom FeCl2·4H2O and elemental sulfur S8in the presence of a tertiary amine as a base was found to catalyze efficiently a 6e?redox condensation ofo-nitrophenols with acetophenones and methylquinolines. The condensed products 2-benzoylbenzoxazoles and 2-quinolylbenzoxazoles were obtained in reasonable yields with water as the only byproduct at a temperature as low as 80 °C.

N-Acylsaccharin represents a facile acyl group transfer agent to heteroarenes in the presence of Pd(II)/NHC complexes appended with a pyrene unit. Catalytic acylation of heteroarenes was enhanced by the noncovalent interaction between the pyrene unit and

An environmentally and economically sustainable synthesis of 2-benzoxazyl ketones and 2-benzothiazyl ketones through FeCl3·6H 2O catalyzed tandem reactions of alkynyl bromides with 2-amino(thio)phenols in [bmim]BF4 has been developed. Remarkable advantages of this new synthetic strategy include high efficiency, readily available starting materials, and recyclable catalyst and reaction medium.
