不对称b-二酮在乙腈中,二氯化-三-联吡啶钌([Ru(bpy)_3]Cl_2,1 mol%)催化下,加入碳酸氢钠(1倍摩尔量)和4A型分子筛,光照条件下通入氧气,反应4 h制得相应的羧酸。18例收率50%~99%。
Asymmetric b-diketone was added sodium bicarbonate (1-fold molar amount) and zeolite 4A in acetonitrile under the catalysis of ruthenium dichloride- [Ru (bpy) 3] Cl 2,1 mol% , Pass the oxygen under light conditions, the reaction 4 h obtained corresponding carboxylic acid. 18 cases of 50% to 99% yield.
