Kuznetsova, Lidia I. published the artcileOxidative Bromination of Alkenes Mediated with Nitrite in Ionic Liquids, Recommanded Product: 2,3-Dibromo-2,3-dimethylbutane, the publication is Catalysis Letters (2014), 144(9), 1499-1506, database is CAplus.
An oxidative bromination of C2-C8 alkenes with HBr-NaNO2-O2 in solutions of BMImBr, HMImBr or BMImBF4 containing 16-28 wt% H2O was studied using a volumetric method, GC-MS anal., 14N NMR and UV-VIS spectroscopy. The optimal conditions to conduct the reaction at high selectivity for 1,2-dibromoalkanes in BMImBr were determined The composition of ionic liquid affects the catalytic performance. Although in BMImBF4 the reaction runs with equal rate as in bromide ionic liquid, the fraction of bromohydrin in the reaction products increases to 20%. Generated from NaNO2, NOx operated as a catalyst in the oxidation of bromide ion (Br–) and was oxidized to catalytically inert nitrate (NO3–) anions when complete conversion of HBr was attained. The synthesis of the target compounds was achieved using 1-butyl-3-methylimidazolium bromide as ionic liquid Alkenes included 1-propene, 1-butene (α-alkenes), 2-methyl-1-propene, cyclohexene, 1-octene, 2,3-dimethyl-2-butene. The title compounds thus formed included 1,2-dibromopropane, 1,2-dibromobutane, 1,2-dibromo-2-methylpropane and similar substances. Alcs., such as 1-bromo-2-propanol, 1-bromo-2-butanol, 1-bromo-2-methyl-2-propanol, 2-bromocyclohexanol, 1-bromo-2-octanol, 2-bromoethanol were also observed Formation of 2,3-dimethyl-2,3-dinitrobutane and 2,2,3,3-tetramethyloxirane was reported.
