How does anisole react with methyl chloride
Webinduced by EWG promotes its cleavage by oxalyl chloride. We further observed that steric hindrance of methyl or isopropyl units attached to the aromatic ring and adjacent to the N-Boc group slows the reaction as seen for entries 2, 5, and 6. More-over, the deprotection reaction of heteroaromatics in entry 11 proceeded modestly in 4 h. WebThis reaction involves the acylation of anisole with an acyl chloride in the presence of anhydrous aluminium chloride as a catalyst. Both these reactions follow the electrophilic substitution reaction. To be precise, in both these reactions, the alkyl and acyl groups are introduced at ortho and para positions by reaction with an alkyl halide ...

WebJan 23, 2024 · Bromination of methoxybenzene (anisole) is very fast and gives mainly the para-bromo isomer, accompanied by 10% of the ortho-isomer and only a trace of the meta-isomer. Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product. Webq Incidentally, chlorine reacts with benzene in an entirely similar way. A few very reactive aromatics, which have very electron-rich rings, are able to react directly with molecular bromine or chlorine, without the need for an electrophilic catalyst. A few very unreactive ones may require the generation of Br++.
