Reaktion von (Z,Z)-1,5-Cyclooctadien mit N-Bromsuccinimid in Gegenwart von Wasser oder MethanolThe action of N-bromosuccinimide (NBS) and water on (Z, Z)-1,5-cyclooctadiene (1) results in the formation ofendo,endo-2,5-dibromo-9-oxabicyclo [4.2.1]nonane (2),endo,endo-2,6-dibromo...
Methods are described for the micro and submicro determination of cyanide and sulphite by oxidation with N-bromosuccinimide to cyanate and sulphate, respectively. In the cyanide method, KI-starch, Methyl Red or Bromothymol Blue can be used as indicator, but for sulphite quantitative results can be...
ChemInform Abstract: RK. VON 2-METHYLEN-NORBORNAN MIT N-BROMSUCCINIMIDaddition reactionsMonochlorocarbene undergoes addition to bicyclo[2.2.2]octene-2 to give anti- and syn-3-chlorotricyclo[3.2.2.02,4]nonane in a ratio of 5:1. On warming the mixture, only the syn isomer rearranges to 2...
The bromination of Δ 4 -3-keto-steroids with the aid of N-bromo-succinimide takes place in 6-position, that is in allyl-position and not in α -position to the keto group. By splitting off hydrogen bromide from these 6-bromo-compounds, Δ 4;6 -3-keto-steroids are obtained in known...
