Abstract The findings of this thesis are presented in four sections First diazotization and diazocoupling reactions of para diazonium benzene sulfonyl azide with aromatic phenols overeco friendly clay catalysts are described These catalysts are inexpensive noncorrosive andreusable Also they have not considerable decreases in the efficiency after four cycles ofoperation The new method totally avoids the use of acids alkalies and toxic solvents indiazotization and diazo coupling reactions After that the synthesis of a new diazo reactivedye containing 4 sulfonyl azide benzenediazonium salt with a variety of couplingcomponents has been done The coupling component used in this reaction are salicylic acid methyl salicylate ethyl salicylate butyl salicylate methyl 2 4 dihydroxy banzoate ethyl2 4 dihydroxy banzoateate salicylamide 2 4 dihydroxy bnanzamide salicylaldhyde salicylaldoxime 2 hydroxyacetophenone respectively The Structures of all of thecompounds were confirmed by FT IR UV 1H NMR 13C NMR mass spectroscopy andelemental analyses Their solvatechromic properties in different solvents were also studied Second the thermal reaction of sulfonyl azide dye with cyclohexane benzene anisole p xylene dihydropyran and pyridine was studied Third diazotization and diazocoupling reaction of para amino benzene sulfonyl azideand para amino benzene sulfonyl amide with cyclic amines with various ring sizes hasbeen done The cyclic amines used in these reactions are pyrrolidine piperidine 4 methylpiperidine N methylpiperazine morpholine and hexamethyleneimine over eco friendly clay catalysts Finally The structure and electronic properties of synthesized compounds in previoussections have been investigated theoretically at the level of AM1 PM3 and HF DFT usingthe standard 6 31 G basis set The optimized structure electronic properties vibrationalfrequencies and relative energies of the molecules were obtained Observed frequenciesobtained from the IR spectrum of each compound have been compared with thosecalculated from theoretical results The observed spectra were found to be in goodagreement with the calculations The effect resonance conformation and ring size of cyclicamine on the conjugation of triazenes were investigated
