2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (CAS: 84-58-2) is used as an oxidizing agent, especially in steroid synthesis.
DDQ has a variety of applications. DDQ is a deprotection agent for ketals, acetals, and thioacetals. It is a useful electron transfer reagent for synthesis of quinolones and an oxidizing agent used to synthesize steroids. Additionally, DDQ is used with Ph3P to synthesize 1,2-benzisoxazoles.
DDQ is a strong oxidation reagent, which is widely used in the dehydrogenation of compounds, especially for steroid compounds. It has good selectivity and is an indispensable oxidation reagent in the steroid industry. With the deepening of the research, it is gradually found that DDQ shows a good application prospect in many organic reactions. For example, selective oxidation of alcohols, oxidation at the benzyl position of the aromatic ring, formation of carbon-carbon bonds, formation of carbon heterobonds, Cyclization Reactions, protection and deprotection, and the like. Used as pharmaceutical intermediates, specifically as dehydrogenation agents for steroid hormone compounds.
DDQ is more and more widely used in organic reactions, and its application fields are also increasing. The development of new application fields, especially the oxidative coupling cyclization reaction, is the main development trend of DDQ in the application research of organic reactions.
DDQ (CAS: 84-58-2) reacts with water to release highly toxic hydrogen cyanide (HCN). A low-temperature and weakly acidic environment increases the stability of DDQ. Need to be stored in a dry state.
