Related Products of 584-13-4, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 584-13-4, name is 4H-1,2,4-Triazol-4-amine, molecular formula is C2H4N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: In a typical experiment Pd(OAc)2 (5.6mg, 0.025mmol), triphenylphosphine (13.2mg, 0.05mmol), iodoalkene (1-4) or iodoarene (5-19) (1mmol) were dissolved in DMF (10mL) under argon in a three-necked flask equipped with a reflux condenser and a balloon on the top. Aminotriazole nucleophile (a, b or c) (1.2mmol) and triethylamine (0.5mL) were added. The atmosphere was changed to carbon monoxide. (Caution: High pressure carbon monoxide should only be used with adequate ventilation (hood) using CO sensors as well.) The reaction was conducted for the given reaction time upon stirring at 70C. The mixture was then concentrated and evaporated to dryness. Toluene (15mL) was added to the residue, the precipitate (product) was filtered, washed with water on the filter and dried. The off-white powder-like material was dissolved in methanol, the palladium-black was filtered off and methanol was evaporated.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 4H-1,2,4-Triazol-4-amine is helpful to your research.
