If you look through the list ofortho- , para-directors, you might recognize that many of them are also activating groups. Likewise, the list ofmeta-directors (nitro, CF3, cyano) is like a who’s who of deactivating groups. If you’re a real nerd, you could even make ...

Amongst the powerful directing groups in Ir-catalyzed C-H borylation are N-containing carbocyclic systems. This review covers substrate-directed Ir-catalyzed ortho-C-H borylation of aromatic C(sp2)-H bonds in N-containing carbocyclic compounds, such as anilines, amides, benzyl amines, hydrazones,...
ortho-, meta-and para-functionalization is tolerated at the arene group which undergoes C-H halogenation. Some modifications are also possible on the 2-(arylsulfonyl) heteroaryl directing groups. A comparison of the halogenation efficiency suggests that bromination is the practical method of choice, ...
