[Cp*Co(CO)I2], which proved highly efficient as catalyst in mechanochemical C−H bond amidations of indoles in a mixer ball mill. A wide range of amidated products is obtained in excellent yields. Compared to the solution‐based methods, the procedure opens a more feasible and environmentally‐friendly access to both the cobalt(III) catalyst and 2‐amidated indoles.

directed heterogeneousC−Hactivation/halogenationreactioncatalyzed by readily synthesized Pd@MOF nanocatalysts was developed. The heterogeneous Pd catalysts used were a novel and environmentally benign Fe‐based metal–organic framework (MOF) (Pd@MIL‐88B‐NH2(Fe)) and the previously developed Pd@MIL‐101‐NH2(Cr). Very high conversions and selectivities were achieved under very mild reaction conditions

AbstractWe report a concise, versatile and practical method for the ortho‐chlorination, ortho‐bromination and ortho‐iodination of aryl compounds. The significant advantage of this transformation is the creation of the carbon‐halogen bond by use of readily available and cheap halide salts as formal nucleophilic halogenating reagents under mild reaction conditions.magnified image
