Silica Supported Phosphomolybdic Acid: An Efficient Heterogeneous Catalyst for Friedlander Synthesis of Quinolines

Abstract

Silica supported phosphomolybdic acid, an eco-friendly heterogeneous catalyst, has been found to be highly efficient for Friedlander synthesis of quinolines in excellent yields. A variety of ketones afford the quinolines smoothly. The catalyst can be easily recovered and reused.
