example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-couplingreactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong
the low reactivity of the Ar–NO2 bond toward oxidative addition. We report here the C–N coupling of nitroarenes and amines using palladium/5-(2,4,6-triisopropylphenyl)imidazolylidene[1,5-a]pyridines as the catalyst. The ligands are readily available from commercial chemicals. The reaction shows broad substrate scope and functionalgroup tolerance. The method is applicable to both aromatic and aliphatic

The easily accessible, air- and moisture-stable cyclopalladatedferrocenylimine complex 3 was found to be a highly active one-component precatalyst for the amination of aryl chlorides in water in the presence of inexpensive KOH and t-BuOH as a base and an additive, respectively.

2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl(Sphos)]-palladacycles containing hydroxymethyl groups 2–3 were prepared by cyclopalladation and chloride bridge-splitting reactions. The complexes were characterized by elemental analysis, ESI–MS and NMR. In addition, single-crystal X-ray analysis reveals that they have one-dimensional lamellar structures involving intermolecular hydrogen bonds and π–π interactions
