A possibility for the formation of product of ...
The potential energy surfaces in gas phase and in aqueous solution for the nitration of benzene, chlorobenzene, and phenol have been elucidated with density functional theory at the M06-2X/6-311G(d,p) level combined with the polarizable continuum solvent model (PCM). Three reaction intermediates...
Highly efficient bromination of aromatic compounds using 3-methylimidazolium tribromide as reagent/solvent. 3-Methylimidazolium tribromide proves to be an alternative highly efficient reagentsolvent for the halogenation of non-activated aromatic compounds.

1. Four-Step Synthesis of HDippL The initial step utilized pyridine and acetyl chloride to protect the alcohol functional group of 2,6-dimethyl phenol. The double bromination of the methyl substituents was then initially attempted at 90 °C using infrared activated N-bromosuccinimide (NBS).13 How...
Lewis acids can make electrophiles even more electron-poor(reactive), increasing the reaction rate. For example FeBr3/ Br2allows bromination to occur at a useful rate on benzene, whereas Br2by itself is slow). Everything we’ve learned so far about substitution on aromatic rings would teach ...
