This thesis describes the synhtesis and characterization of tripropargylamine and its derivatives. Preparation of tripropargylamine was succesfuly achieved with nucleophilic substitution of ammonium hydroxide with propargyl bromide at the elevated temperature. Later we prepared 1,4-disubstituted-1,2,3-triazoles, using previously prepared tripropargylamine in combination with three aromatic azides, For preparation of triazoles we used copper-catalyzed alkyne-azide cycloaddition (CuAAC), which we catalyzed with Cu(OAc)2·H2O. Using diariliodonium salts and anhydrous CuSO4 as a catalyst, we successfuly prepared a series of arylated 1,3,4-trisubstituted-1,2,3-triazolium salts from TBTA molecule and its derivates. Procedure also proved successful in a case of using diariliodonium salts with electrondonor substituents.
