Research On The Free-Radical Reactions By Mn(Ⅲ) And The Synthesis Of Triazole Compounds

In this thesis, two series compounds of 2-aminoaroyl pyrido[2,3-b] thiazoles (2a～2l) and thiadiazoles (4a～4f) were synthesized by using the reagent of manganese triacetate. We also applied it to do thiocyanation of aromatics and heteroaromatics, and got (6a～6j) and (8a～8h). Then we developed a microwave-assisted, catalyst-free and solvent-free reaction for the synthesis ofα-amino phosphonates (9a～9l).In addition we studied on the cyclic reaction between 1-benzoyl-3-arylthioureas and hydrazine hydrate, and a series compounds of triazoles (11a～11g) were synthesized. All the structures of new compounds were confirmed by 1H NMR, 13C NMR and HRMS spectra.
