Aryl and heterocyclic stannanes ArSnMe3 were prepared by a Sandmeyer-type diazotization-stannylation reaction of aromatic amines ArNH2 with tBuONO and distannane Me3SnSnMe3. The reaction proceeds in mild conditions, using 1.5 equiv of the diazotization reagent, tert-Bu nitrite in 1,2-dichloroethane solution and is promoted by Bronsted or Lewis acids, optimally, by 1.2 equiv of TsOH. The reaction proceeds via radical intermediates, as shown by complete inhibition with 1.5 mol equiv of TEMPO. The yields of electron-deficient aryl and heterocyclic stannanes were generally lower, which were explained by longer time required for diazotization of the corresponding amines. The results came from multiple reactions, including the reaction of 6-Bromopyridin-3-amine(cas: 13534-97-9Product Details of 13534-97-9)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.Product Details of 13534-97-9
