Abstract
Przedmiotem wynalazku jest sposób otrzymywania 3-podstawionych pochodnych ?-diketonów o ogólnym wzorze 1, w którym R oznacza podstawiona i niepodstawiona grupe benzylowa lub podstawiona grupe allilowa i metalillowa. Sposób polega na reakcji odpowiedniego zwiazku chlorowcopochodnego z sola acetyloacetonu w wodzie lub w wodzie z dodatkiem polarnych rozpuszczalników organicznych mieszajacych sie z woda. Wariantem wynalazku jest sposób polegajacy na wytwarzaniu soli acetyloacetonu bezposrednio w srodowisku reakcji zarówno w wodzie jak i w mieszaninach wody z rozpuszczalnikiem organicznym. The present invention relates to a process for the preparation of 3-substituted derivatives of α-diketones of the general formula I, wherein R is a substituted and unsubstituted benzyl group or a substituted allyl and metalyl group. The method consists in reacting the appropriate halogenated compound with a salt of acetylacetone in water or in water with the addition of polar organic solvents miscible with water. A variant of the invention is the method of producing acetylacetone salts directly in the reaction medium both in water and in mixtures of water with an organic solvent.
