The study presents a novel, catalyst-free mechanochemical protocol for synthesizing 2,3-dihydro-1H-perimidines, utilizing 1,8-diaminonaphthalene and various aldehydes. These chemicals are ground together using a mortar and pestle for 5 minutes, yielding the desired products in moderate to excellent yields without the need for conventional solvents or catalysts. The methodology is environmentally friendly and energy-efficient, highlighting the green chemistry principles. The synthesized perimidines, known for their diverse biological and material properties, are expected to be further investigated for their potential applications in areas such as antifungal, antimicrobial, and photochromic materials.
