Method The target compound was synthesized from clarithromycin via hydrolyzation,acetylation,cyclic carbonatation,oxidation,decarbonatation,acylation,cyclic carbamatation and cyclization.
Thestabilized powders have obvious better oxidation resistance than unstabilized Pow-ders.And the other physical and chemical properties remain constant.
The oxidation,displacement and esterification of aromatic amines,aromatic amides and organic boranes using sodium perborate as oxidizing agent were reviewed.
In the oxidation reaction of cyclohexene, total selection of cyclohexene oxide, cyclohexanol, cyclohexenol and 2-cyclohexene-l-one reaches 98.5%, conversion reaches 33.2%.
Coordination Chemistry: Characterization of the electronic structure and the bonding characteristic of nonplanar metalloporphyrins in different oxidation and spin states.
This thesis mainly introduced that ureas and semicarbazides were synthesized by oxidation of corresponding thioureas and thiosemicarbazides using 30% peroxide as oxidant.
