PhI(OAc)2 in the presence of OsO4 (cat.) and 2,6-lutidine cleaves olefinic bonds to yield the corresponding carbonyl compounds, albeit, in some cases, with α-hydroxy ketones as byproduct. A more practical and clean protocol to effect oxidative cleavage of olefinic bonds involves NMO, OsO4 (cat.), 2,6-lutidine, and PhI(OAc)2.
PhI(OAc) 2在OsO 4 (cat.)和2,6-二甲基吡啶的存在下裂解烯键以产生相应的羰基化合物,尽管在某些情况下,副产物为α-羟基酮。影响烯烃键氧化裂解的更实用和更干净的协议涉及 NMO、OsO 4 (cat.)、2,6-二甲基吡啶和 PhI(OAc) 2。
