Abstract: α,α′-bis(substituted benzylidene)cycloalkanones were efficiently prepared from variously substituted aldehydes and cycloalkanones in water by using ash of pomegranate peels (APP) as a catalyst. The APP-catalyst was obtained from bio-waste by simple thermal treatment to dry peels of pomegranate fruit and formation of its active phase was confirmed by FT-IR, XRD, XRF, EDX, SEM, DSC-TGA and BET techniques. The analysis revealed that the present catalyst has basic sites which promote the synthesis of desired products. The main attractions of our protocol are utilization of highly abundant bio-waste-derived catalyst and good-to-excellent yield in shortest reaction time. This green protocol was further extended for structurally diverse 2-arylidene-1-tetralones by condensation of equimolar quantity of aromatic aldehydes and 1-tetralone at low temperature. The catalyst could be quantitatively recovered and reused effectively for five times. Graphic abstract: [Figure not available: see fulltext.].

Benzylidine tetralones have been synthesized in excellent yields in PEG 600 at room temperature and short time periods. The synthesized compounds are found to have antibacterial activity towards both gram-positive and gram-negative bacteria. The N, N-dialkyl substituted benzylidine tetralones are found to possess fluorescent properties.
