Furanyl bis(indolyl)methane as a palladium ion-selective chromogenic agent

Abstract

The colorless solution of furan-2-yl bis(indolyl)methanes (BIMs) were newly reveled to work as palladium (Pd2+) ion-selective chromogenic agent to turn orange. 5-(N-methyl-N-phenyl-aminomethyl)-furan-2-yl BIM could be synthesized from 5-chloromethylfurfural as a...
