In organic chemistry, the Baudisch reaction is a process for the synthesis of nitrosophenols using metal ions. Although the products are of limited value, the reaction is of historical interest as an example of metal-promoted functionalization of aromatic substrates. ==History== As described originally by Oskar Baudisch in 1939 and further developed by his colleague Cronheim in 1947, benzene, hydroxylamine, and hydrogen peroxide are combined. Baudisch proposed that o-nitrosophenols are formed when a "nitrosyl radical" NOH, inserts a C-H bond followed by the oxygenation at a position ortho to the nitroso group. The nitrosylating agent can be generated from three different nitrogen sources, all requiring presence of hydrogen peroxide: #oxidation of hydroxylamine hydrochloride with cupric ions. #reduction of nitrous acid with cuprous ions. #the action of cuprous ions and hydrogen peroxide on benzenesulfo-hydroxamic acid. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Baudisch reaction」の詳細全文を読む スポンサード リンク
