Organocatalytic oxidative dehydrogenation of dihydroarenes by dioxygen using 2,3-dichloro-5,6-dicyano-benzoquinone (DDQ) and NaNO2.
The oxidative dehydrogenation of dihydroarenes catalyzed by 2,3-dichloro-5,6-dicyano-benzoquinone(DDQ) and NaNO(2) with dioxygen is reported. The combination of DDQ and NaNO(2) showed high efficiency and high selectivity, compared with other benzoquinones and anthraquinones, e.g., >99% conversion of 9,10-dihydroanthracene with 99% selectivity for anthracene can be obtained at 120 degrees C unde...

متن کاملSpectrophotometric Determination of Drugs Using 2,3-Dichloro 5,6-dicyano p- benzoquinone as Analytical Reagent
Six drugs viz., Astemizole, Domperidone, Esomeprazole, Losartan potassium, Sumatriptan and Terazosin were tested for the formation of charge transfer complexes with 2, 3-dichloro 5, 6-dicyanopbenzoquinone, (DDQ). Each of these drugs turned the pale yellow colour of reagent i.e DDQ. in CH3CN, to purple and exhibited three bands at 455, 545 and 588 nm due to anion of the reagent whose intensity i...
متن کاملMild Method for 2-Naphthylmethyl Ether Protecting Group Removal Using a Combination of 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and β-Pinene
The use of a combination of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and β-pinene permits the removal of 2-naphthylmethyl (Nap) ether protecting groups on highly sensitive substrates. The reaction tolerates both acid and base sensitive protecting groups, and products are afforded in 68-96% yield. The utility of the method is demonstrated by the removal of the Nap protecting groups on hig...
متن کاملOxidative functionalization of benzylic C–H bonds by DDQw
C–H activation of the methyl group of toluene and related ArCH3 derivatives by 2,3-dichloro-4,5-dicyano-1,4-benzoquinone (DDQ) gives insertion products, ArCH2O[C6Cl2(CN)2]OH via a rate-determining hydride abstraction by DDQ. The resulting benzylic ether can undergo reactions with phosphines to give benzylic phosphonium salts (Wittig reagents) and with phosphites to give phosphonate esters (Horn...
