Abstract

Abstract : The polystyrene supported palladium (Pd@PS) nanoparticles catalyzed decarboxylative coupling of arylhalides and alkynyl carboxylic acids was developed for the synthesis of diaryl alkynes, indoles and pyrrolines. Abstract : The polystyrene supported palladium (Pd@PS) nanoparticles (NPs) catalyzed decarboxylative coupling (DC) of arylhalides and alkynyl carboxylic acids was developed for the synthesis of diaryl alkynes. Indole and 3-pyrroline heterocycles were also synthesized from 2-iodo anilines/amino benzocycloheptene bromide and alkynyl carboxylic acids, following a domino decarboxylative coupling-cyclization (DCC) approach under the same catalytic conditions. The combined anchoring and catalytic behaviour of Pd@PS makes the process favourable for the product formation.
