An efficient solvent-free synthesis of bis(indolyl)methane-based naked eye chemosensor for Cu2+ion from β-chloro-α,β-unsaturated aldehydes using PMA-Cellulose as a solid phase reusable catalyst

Abstract

A green one pot synthesis of novel bis(indolyl)methanes as naked eye chemosensors towards Cu2+ion has been developed from β-chloro-α,β-unsaturated aldehydes using new reusable solid acid support/catalyst PMA-Cellulose.
