Synthesis of hindered alkyl aryl ether derivatives (R–O–Ar) remains a huge challenge and highly desirable in organic and medicinal chemistry because extensive substitution on the ether bond prevents the undesired metabolic process and thus avoids rapid degradation in vivo. Herein, we report an unprecedented hindered alkoxylation of picolinamide attached aromatic amines using economic copper salt and

Aminocarbonylation of arylhalides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the development of nickel catalysis for the first three-component reactions of arylhalides, Co2(CO)8, and nitroarenes under reductive conditions to produce aryl amides. A

work, we report the synthesis of these functional groups via an iron(iii) chloride-catalyzed direct amidation of esters. The reactions are conducted under solvent-free conditions and found to be compatible with a range of amine and ester substrates generating the desired amides in short reactiontimes and good to excellent yields at a catalyst loading of 15 mol%.
The preparation and X‐ray structural characterization of aliphatic amino iodane (III) reagents has been realized. These new reagents could be used for the Cu‐catalyzed directed electrophilic amination of aryl amines.
