Demonstrates effective synthesis of benzoxazoles and benzimidazoles, indicating green chemistry benefits.
A green and efficient reductive cyclization process of ortho-nitro compounds was developed by triethylsilane (TES) under air conditions in the presence of catalytic Pd/C. A series of benzimidazole and benzoxazole derivatives was achieved in good to excellent yields.
