Condensation of 2-cyanomethyl benzaldehydes 1 with 2 (ammonia, primary or secondary amines) carried out in the presence of a catalytic amount of trifluoroacetic acid, afforded 3aminoisoquinolines 3. In the case of primary amines azomethines 4 were formed at first, they dissociated and subsequently yielded 3 in a rather slow process.

A base-promoted amination of aromatic halides has been developed using a limited amount of dimethylformamide (DMF) or amine as an amino source. Various arylhalides, including F, Cl, Br, and I, have been successfully aminated in good to excellent yields. Although the amination of aromatic halides with amines or DMF is usually considered as an aromatic nucleophilic substitution (SNAr) process, and the

silylated: In the presence of iridium or rhodium catalysts, C(sp3)H bonds adjacent to a nitrogen atom were silylated by the aid of a pyridine‐directing group. In iridium catalysis, a hydrogen‐trapping reagent such as norbornene or tert‐butylethylene, which is usually required in late transition‐metal‐catalyzeddehydrogenative coupling reactions, was not required. In rhodium catalysis, however, 1 equivalent
