Adding some certain compound to certain chemical reactions, such as: 27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 27996-86-7. 27996-86-7
A mixture of alpha ionone (1.152 g, 1.23 ml, 6 mmol), 4-(1H-1,2,4-triazol-1-yl) benzaldehydes (0.865 g, 5 mmol), cetyltrimethyl ammonium bromide (0.070 g, 0.5 mmol), sodium hydroxide (0.600 g, 15 mmol) and water (25 ml) was stirred at room temperature for 24 h. Reaction progress was monitored by TLC and compound was extracted with ethyl acetate (2 ¡Á 50 ml). The combined organic extract was washed with water (2 ¡Á 50 ml), brine solution (50 ml), dried (Na2SO4) and the solvent was removed in vacuum. The crude product was purified by column chromatography (SiO2, 60-120 mesh). Elution with 10 % ethyl acetate in hexane furnished a pale yellow coloured solid (0.400g, 23%).
