Aminated and recycled: Palladium/imidazolium phosphane catalysts enable efficient and general aminations of arylhalides, including direct amination with ammonia. Subsequent recycling is possible without any additional heterogenization (see scheme).

A new robust transition‐metal‐free method for synthesis of 1,2‐disubstituted indoles from easily available tertiary amides is presented. This approach can be performed in a one‐pot two‐step manner directly from secondary amines. Mechanistic studies showed that acyl transfer might be an important step in the course of the reaction. Viability of the presented approach for benzofurans and benzothiophenes

The photostimulated reaction of N-(2-halo-benzyl)aryl amines with t-BuOK in liquid ammonia affords fused azaheterocycles by the SRN1 mechanism. The starting materials are easily obtained by the reaction of 2-halo-benzyl chloride and aromatic amines to prepare the secondary amines. Through this approach, phenanthridine (90%), 4-phenylphenanthridine (87%), benzo[a]phenanthridine (98%), and benzo[c]phenanthridine
