Abstract

Invenţia se referă la domeniul chimiei, în particular la un procedeu de obţinere a compuşilor bioactivi, care pot fi utilizaţi pentru reglarea creşterii plantelor.Procedeul include diazotarea derivatului aminobenzenului sau a acidului orto-aminobenzensulfonic, urmată de cuplarea omogenă catalizată de paladiu şi hidrogenarea eterogenă catalizată de paladiu, totodată catalizatorul omogen este redus şi sedimentat sub formă de metal după reacţia de cuplare, care se utilizează fără izolare în calitate de catalizator eterogen de paladiu pentru hidrogenare.Rezultatul tehnic constă în mărirea eficienţei procedeului datorită utilizării catalizatorului de paladiu în treapta reacţiei omogene şi în treapta reacţiei eterogene de hidrogenare.The invention relates to the field of chemistry, in particular to a process for obtaining bioactive compounds, which may be used to regulate plant growth. The process includes diazotation of the aminobenzene derivative or ortho-aminobenzenesulfonic acid, followed by homogeneous coupling catalyzed by palladium and hydrogenation of palladium, at the same time the homogeneous catalyst is reduced and sedimented in metal form after the coupling reaction, which is used without isolation as heterogeneous palladium catalyst for hydrogenation. The technical result consists in increasing the efficiency of the process due to the use of the palladium catalyst in the homogeneous reaction step. and in the step of heterogeneous hydrogenation reaction.
