New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 930-33-6, name is 1H-1,2,4-Triazol-3(2H)-one belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 930-33-6
To a mixture of l,2-dihydro-5H-l,2,4-triazol-3-one (5.74 mmol) in toluene (70 ml), al- pha,alpha-diphenylbenzenemethanol (4.7 mmol) and p-toluenesulphonic acid (1.91 mmol) were added. The reaction was heated at reflux using a Dean-Stark separa- tor under Nitrogen atmosphere for 20 hours. The solution was cooled and quenched with 2 % of an aqueous solution of NaHCO3 and extracted with CH2Cl2 (3×100 ml). The organic layer was separated, dried (Na2SO4) and the solvent evaporated. The resi- due was purified by column chromatography (eluent: CH2Cl2/Me0H 9/1). Yield: 925 mg of intermediate compound 26 (60 %).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1H-1,2,4-Triazol-3(2H)-one help many people in the next few years.
