In benzyl group electron donating
WebBoth electron-withdrawing (enolisable para-acetyl group) 370 and electron-donating substituents (para-methoxy) 371 on the arylboronic acid substrate were well tolerated. In their attempt to realise an alkylacylation reaction with the formation of challenging C(sp 3 )–C(sp 3 ) bonds, alkylboronic acid was used but instead produced a ...

WebSuch a ring needs to have a strong electron donating group like OH or NH 2 to increase its reactivity in an electrophilic aromatic substitution mechanism. The product of the electrophilic coupling of a diazonium ion with a reactive aromatic ring includes a nitrogen-nitrogen double bond. These compounds are often intensely colored and are useful ... WebThe present paper is a commentary on the electronic effects that protecting groups exert on glycosylation chemistry. Specifically, its purpose is to rectify the misguided use of the term electron donating benzyl groups, which hardly makes sense in the context of protecting groups on alcohols in saturated systems such as carbohydrates.
