starch-SO3H and montmorillonite-SO3H (MMT-SO3H) were used as solid acid catalysts for the synthesis of 2-amino-5-aryl-azothiazole dyes from the diazo coupling reactions of aromatic amines with 2-aminothiazole. The experimental results showed among studied solid acids, MMT-SO3H was the most effective nanocatalyst in this process. This efficient approach offers attractive advantages, such as excellent yields and
