Abstract: A series of new 1, 2/1, 3-bis [o-(N-methylidenamino-3-aryl-5-phenyl-4H-1, 2, 4- triazole-4-yl) phenoxy] ethane/propane derivatives 4 were prepared in good yields by treatment of 4-amino-3-aryl-5-phenyl-4H-1, 2, 4-triazoles 2 with certain bis-aldehydes 1. Compounds 4 were reduced with NaBH 4 to afford the corresponding 1, 2/1, 3-bis [o-(N- methylamino-3-aryl-5-phenyl-4H-1, 2, 4-triazole-4-yl) phenoxy] ethane/propane ...
