A simple method for directC–H imidation is reported using a new perester-based self-immolating reagent and a base-metal catalyst. The succinimide products obtained can be easily deprotected in situ (if desired) to reveal the corresponding anilines directly. The scope of the reaction is broad, the conditions are extremely mild, and the reaction is tolerant of oxidizable and acid-labile functionality

Quantitative benzylic mono- and gem-dibromination on primary aromatic amine derivatives have been achieved using molecular bromine and by protecting the amino group as a succinimide moiety. The reactions of N-(o/m/p-tolyl)succinimides 5a-c with 1.25 equivalents of molecular bromine in CCl4 at room temperature furnished the corresponding benzylic monobrominated products 6a-c in 92-94% yields, while with 2.5 equivalents of molecular bromine in refluxing CCl4 gem-dibromo products 7a-c were obtained in 94-96% yields. It is also possible to carry out nuclear bromination in these N-protected primary aromatic amines at an alternate site by using suitably substituted aniline derivatives. Thus the reaction of 3 with 1.25 equivalents of molecular bromine in acetic acid gave the desired monobrominated product 4 in nearly 100% yield.
