The article was titled 《SO2F2-mediated oxidation of primary and tertiary amines with 30% aqueous H2O2 solution》.Recommanded Product: 626-40-4 The article contains the following contents:
A highly efficient and selective oxidation of primary and tertiary amines employing SO2F2/H2O2/base system was described. Anilines were converted to the corresponding azoxybenzenes I [R = H, 4-Me, 3-Cl-4-Me, etc.], while primary benzylamines were transformed into nitriles ArC≡N [Ar = Ph, 4-ClC6H4, 4-MeOC6H4, etc.] and secondary benzylamines were rearranged to amides ArNHC(O)R1 [Ar = Ph; R1 = Me, Et]. For tertiary amine substrates quinolines, isoquinolines and pyridines, their oxidation products were the corresponding N-oxides II [R1 = R2 = Me; R3 = Me, Ph], III [R4 = H, 7-Me, 6-NO2; R5 = 2-Me, 3-Me, 4-Me], IV [R6 = H, 8-Cl, 6-Br] and V [R7 = H, 2,6-di-Me, 4-MeO, 2-Br, 4-oxiran-2-yl]. The reaction conditions were very mild and just involve SO2F2, amines, 30% aqueous H2O2 solution, and inorganic base at room temperature One unique advantage was that this oxidation system was just composed of inexpensive inorganic compounds without the use of any metal and organic compounds The results came from multiple reactions, including the reaction of 3,5-Dibromoaniline(cas: 626-40-4Recommanded Product: 626-40-4)
3,5-Dibromoaniline(cas: 626-40-4) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).Recommanded Product: 626-40-4
