However, when bromine water is added to an aqueous solution of phenol, a white precipitate with an antiseptic smell is formed. What is the explanation for this difference? A Bromine is a powerful electrophile.B B The benzene ring in phenol is activated. C The reaction of phenol with bromine...
Bromination of benzo[b]quinuclidine yields its perbromide and a molecular complex with bromine, while nitration and chlorosulfonation form 7-nitro- and 7-chlorosulfobenzo[b]-quinuclidines. The results of electrophilic substitution attest to the absence in benzo[b]-quinuclidine of a mesomeric ...

For example, reagents such as bromine react with benzene by substitution rather than addition. Benzene and its derivatives had long been referred to as aromatic because of their distinctive odors. The structure for benzene is often shown as a hybrid of the two Kekulé formulas: ...
8.04.3.3 The Improved Synthesis of SCH 5104822 The Friedel–Crafts reaction of 2,4-difluorobenzene with succinic anhydride yielded the ketoacid 48, which was converted in Wittig reaction to the olefin 49 (Scheme 9). Stereoselective hydroxymethylation of 50 obtained from 49 yielded 51. Iodocyclizat...

Competing pathways in the reaction of benzenediazonium ion with azide anion helped to establish the occurrence of phenylpentazole. Steady state kine- tics clarified the competition between the interception of an intermediate and its return to the starting material. The Diels- Alder reactions of ...
Bromine reacts with ethane by afree radicalmechanism. Write the steps of this mechanism. Regioselectivity of Alkane Halogenation The chlorination of higher-molecular-weight alkanes yields a mixture of isomeric monochlorinated products. For example, the chlorination of butane or 2-methyl-propane, which ...
