Application of Sulfonic Acid Functionalized Nanoporous Silica (SBA-Pr-SO3H) for One-Pot Synthesis of Quinoxaline Derivatives

Abstract

Sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) with pore size 6 nm was proved to be an efficient heterogeneous nanoporous solid acid catalyst in the synthesis of quinoxaline derivatives from the reaction of o-Phenylenediamines with 1, 2-diketone compounds in very good yields.
