2.Burgess reagent is an efficient dehydrogenation reagent, which can be used for the preparation of compounds from formamide and nitroalkanes to isocyanitrile and nitrile oxide. In recent years, the biggest use of Burgess reagent is to achieve the cyclization dehydrogenation reaction of hydroxyl amide and thiamide to obtain corresponding heterocyclic compounds.2.Burgess reagent is an efficient dehydrogenation reagent, which can be used for the preparation of compounds from formamide and nitroalkanes to isocyanitrile and nitrile oxide.
