The present study reports a simple, highly efficient and green approach for the synthesis of a series of benzimidazole-acrylonitrile derivatives 3(a–l). The synthetic methodology involves a microwave-assisted reaction exploring novel silica-supported SBPTS as a heterogeneous, proficient and reusablecatalyst resulting in excellent yields. The reaction transformation presumably occurs via a Knoevenagel
