Silica Supported ۱-(۲-(Sulfooxy)ethyl)pyridin-۱-ium Chloride (SiO۲/[SEP]Cl) as an Efficient and Solid Acid Catalyst for the Synthesis of Quinoxaline Derivatives

Silica supported ۱-(۲-(sulfooxy)ethyl)pyridin-۱-ium chloride has been explored as highly efficient catalyst for reactions under mild and green conditions for the synthesis of quinoxaline derivatives. The green and mild methods offer appealing attributes such as use of a recyclable, use of EtOH as green solvent and ۶۰ °C condition, short reaction times, a simple workup and high yield of the products.
