In heterogeneous catalysis, the catalyst is in a different phase from the reactants. category: Isoxazoles, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1123-49-5, name is 3,5-Dimethyl-4-nitroisoxazole. In an article£¬Which mentioned a new discovery about 1123-49-5
THE DIFFERENTIAL REACTIVITY OF 5- AND 3-METHYL GROUPS IN THE REACTION OF 4-SUBSTITUTED 2,3,5-TRIMETHYLISOXAZOLIUM SALTS WITH AROMATIC ALDEHYDES.
2,3,5-Trimethylisoxazolium salts with electron-withdrawing groups at C-4 react with aromatic aldehydes to give 3- and/or 5-arylidene derivatives resulting from the condensation at CH3-3 and/or CH3-5.The differential reactivity of 3- and 5-methyl groups is markedly influenced by the nature of the substituent at C-4 and varies in the same order as its kinetic acidity which was estimated from studies on deuteriodeprotonation.The influence of inductive, resonance and steric effects due to the 4-substituents on the course of the reaction is shown.
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 1123-49-5, help many people in the next few years.category: Isoxazoles
