ligand-free conditions, namely, hydroaminocarbonylation of olefins, aminocarbonylation of aryliodides and oxidative carbonylation of amines, which almost cover all the known mechanisms in carbonylation reactions. Notably, the bulk Pdcatalyst system exhibited better catalytic activity than the classical homogeneous PdCl2/(2-OMePh)3P catalyst system. This study will create a momentous and new field of green

An sp2/sp3 get‐together: A novel and efficient method can be used to synthesize 3,3‐disubstitued oxindoles by the direct intramolecular oxidative coupling of an aryl CH and a CH center (see scheme; DMF=N,N‐dimethylformamide).
