In this video, I have explained the DDQ (2,3-Dichloro-5,6-dicyano-1,4-benzoquinone) mediated oxidation reaction. In fact, DDQ is an electron-deficient molecule due to the presence of an electron-withdrawing group (EWG) like two carbonyl (C=O), two chlorine (Cl) and two cyano (CN). Additionally, after the achievement of two electrons, the molecule itself acquires aromatic stabilization which is the main driving force for the reaction. This property makes it a selective metal-free reagent for oxidation. Links for some other related videoes are provided below. Audiences are requested to watch them.
