WebAn ipso nitration of aryl boronic acid derivatives using fuming nitric acid as the nitrating agent provides efficient and chemoselective access to a variety of aromatic nitro compounds. Preliminary reported reactions with different activating agents likely generate anhydrous HNO 3 as common active reagent and the •NO 2 radical as the active ... WebReactions can be carried out at higher temperatures (−78 °C) if lithium dicyclohexylamide is used to generate the trichloromethyllithium from trichloromethane in the presence of the carbonyl ( Equations (120)– (123) ). Equation (123) gives equally good results with tribromomethane in place of trichloromethane < 74JA3010 >. (120) (121) (122)

Trichloromethyl Group - an overview ScienceDirect Topics
The attachment of an entering group to a position in an aromatic compound already carrying a substituent group (other than hydrogen). The entering group may displace that substituent group but may also itself be expelled or migrate to another position in a subsequent step. The term 'ipso-substitution' is not used, since it is synonymous with substitution. A classic example is the reaction of salicylic acid with a mixture of nitric and sulfuric acid to form picric acid.
