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.
