For example, pyrrolo[2,3-b]pyridine (4) reacts with bromine in chloroform at 0 °C to give the 3-bromo derivative which is unchanged by sodium iodide in acetone, or hot dilute hydrochloric acid (which hydrolyzes 3-bromoindole) 〈68AHC(9)27〉. Compounds (33; R = H, PhCO) also ...
What is observed when chlorine reacts with potassium bromide? Why can't this amino be a nucleophile? Why is bromobenzene nonreactive under both S_N1 and S_N2 conditions? Why should the funnel be removed from the top of the burette while the titration is being performed?
In examples, sodium cyanate is reacted with p-xylylene dichloride in the presence of potassium bromide, sodium bromide and potassium iodide, the solvent being N,N-dimethyl formamide. The polyisocyanates may be used to prepare ... PA Argabright,VJ Sinkey,BL Phillips - US 被引量: 3发表: ...

Step-by-Step Text Solution:1. Identify the Reactants: The reactants in this reaction are aniline (C6H5NH2) and bromine water (Br2 in H2O).2. Understanding the Reaction: When bromine wate
Bromine : iodine.-Water-soluble colloidal forms of iodine and bromine are obtained by causing the halogen to react with gallic or tannic acid to produce hydrogen halide, converting this into an insoluble metallic halide, and decomposing this to yield the halogen in a colloidal and probably ...
An indirect spectrophotometric method for the microdetermination of iodine or bromine in organic compounds is described. The method is based on an oxygen flask combustion yielding iodide or bromide, which is then reacted with an excess of potassium iodate or potassium bromate in acidic medium. The...
