Highly Active, Well-Defined (Cyclopentadiene)(N-heterocyclic carbene)palladium Chloride Complexes for Room-Temperature Suzuki-Miyaura and Buchwald-Hartwig Cross-Coupling Reactions of Aryl Chlorides and Deboronation Homocoupling of Arylboronic Acids
class of well‐defined N‐heterocyclic carbene (NHC)‐(cyclopentadiene)palladiumchloride complexes such as CpPd(NHC)Cl wasw synthesized from the readily available starting NHC‐palladium(II) chloride dimers. These air‐stable, coordinatively saturated NHC‐Pd complexes bearing the cyclopentadiene (Cp) unit exhibit high catalytic activity in the roomtemperatureSuzuki–Miyaura and Buchwald–Hartwig cross‐coupling

Direct coupling of aryl halides with sec-alicyclic amines promoted by CsOH·H2O in DMSO to the corresponding aryl substituted amines, with good to excellent yields, is reported herein. A variety of aryl halides and sec-alicyclic amines with a broad range of electronic diversity and functional groups was studied in this transformation, thus offering general applicability in organic synthesis.
