Synthesis of Azine- and Hydrazone-Based Triarylmethanes

Firstly, a series of new formylated-triarylmethanes (FTRAMs) were synthesized via the Friedel-Crafts reaction of arenes with terephthalaldehyde or isophthalaldehyde in the presence of silica sulfuric acid (SSA) under solvent-free conditions. Secondly, a series of new azines and hydrazones derivatives of formylated-triarylmethanes were synthesized in good yields. The structures of all the compounds were confirmed by elemental analysis, IR, H-1 NMR and C-13 NMR spectroscopy. [GRAPHICS] .
