Synthesis of brominated 2-(tert-butyl-NNO-azoxy)anilmes
摘要:
2-(tert-Butyl-NNO-azoxy)aniline was prepared by selective reduction of 2-(tert-butyl-NNO-azoxy)nitrobenzene. Its bromination yielded the corresponding para-bromo- and ortho,para-dibromoanilines (3a,b). meta-Bromoanilines (6a,b) were synthesized by selective replacement of the ortho-bromine atoms in ortho,para-bromo(tert-butylazoxy)benzene (5a,b) by ammonia in toluene under pressure.
