Description The thioamide represented by the model compound N3,N3-(3-oxapentan-1,5-diyl)-N1-(2-phenyl-3,4-dihydro-quinazolin-4-ylidene)thiourea contain both multi-functional nucleophilic and electrophilic characters. It reacts regioselectivity with amines, amines in the presence of H2O2 and alkyl halides to give the transamination reaction products, the oxidative desulfurization products and the S-alkyl product, respectively. FTIR, 1H NMR, 13C NMR, mass spectroscopy and X-ray identified compounds.
