  The first step of the synthesis involves mixing salicylic acid with ethanoic anhydride. This reaction would be very slow without a catalyst. In this case just a few drops of sulphuric acid added to the mixture means that there are some free positive hydrogen ions in the solution which can bind to the ethanoic ://   Schiff bases and complexes are today the subject of many studies because of the established biological, inhibitor and catalytic properties. The aim of this paper is to investigate the interaction of Schiff base obtained by reaction of 2,2-dihydroxyindane-1,3-dione (ninhydrin) and the essential amino acid tryptophan with copper(II) ion.
