Abstract

Inventia se refera la un procedeu de preparare a unor derivati de 2-benzoil-1, 3, 5-ciclohexantrione prin reactia unei trione cu un compus benzoil substituit, în raport molar de 1 : 1, la 0...50 degree C, în mediu de dimetilformamida, esterul enolic format reactioneaza apoi cu 1...4 mol baza moderata aleasa dintre trialchilamine cu 1...6 atomi, pirida, carbonat sau fosfat de sodiu si cu 0,01...0,5 mol sursa de cianura aleasa dintre cianuri alcaline, cianhidrine, cianura de zinc sau acid cianhidric la 20...40 degree C.The invention relates to a process for the preparation of 2-benzoyl-1,3,5-cyclohexanetriones by reacting a trione with a substituted benzoyl compound in a molar ratio of 1: 1 to 0 ... 50 ° C, in the dimethylformamide medium, the enolic ester formed is then reacted with 1-4 mol of the moderate base chosen from 1 to 6 trialkylamines, pyridine, carbonate or sodium phosphate and from 0.01 to 0.5 mol of the source of the cyanide chosen from alkali cyanides, cyanohydrins, zinc cyanide or hydrogen cyanide at 20 ... 40 degrees C.
