“…[39] The latter was used to convert hydrobromic acid (entry 20), [40,41] which can also be oxidised by using Oxone (2 KHSO 5 ·KHSO 4 ·K 2 SO 4 , entry 21). [42] Oxone is applied directly during the synthesis to convert the alkene into the dibromide (entry 21, [42] entry 22 [43] ), but also to regenerate the reagent, which is a carrying agent (entry 10b), [29] an N-halo compound (entry 23), [44,45] or another N-halo compound, Nbromsuccinimide (NBS, entry 24). [46] Overviews of applications of the oxidants sodium perborate, [50][51][52] CAN, [53][54][55][56] Selectfluor [57,58] and other N-halo reagents, [59] sodium periodate, [60] DIB as a polyvalent iodine compound [61][62][63][64] and Oxone [65,66] can be found in the litera- ture.…”
