An efficient synthesis of tertiary amides from aryl boronic acids and inert tertiary amines through the oxidative carbonylation via C­(sp3)–N bond activation is presented. This protocol significantly restricts the homocoupling biarylketone product. It involves the use of a homogeneous PdCl2/CuI catalyst and a heterogeneous Pd/C based catalyst, which promotes C­(sp3)–N bond activation of tertiary amines with aryl boronic acids. This process represents a ligand-free, base-free, and recyclable catalyst along with an ideal oxidant like molecular oxygen.

This work reports the phenoxy carbonylation reactions for the synthesis of aryl esters using magnetically separable nickel supported on Fe3O4. The two main advantages of this process are the use of an inexpensive nickel catalyst and the application of o‐chlorophenyl formate as a both CO source and phenol as a coupling partner. This catalyst is entirely magnetically separable due to the super paramagnetic nature of Fe3O4 and decent reusability potential for up to eight cycles with minimal drops in yields. This protocol tolerates various functionalities of aryl iodides and provided moderate to good yields of corresponding esters. The as‐prepared Ni/Fe3O4 nanoparticles have been characterized using analytical techniques such as FESEM, EDS, TEM, XRD, ICP‐OES, and XPS.

We report Pd/C-catalyzed oxidative aminocarbonylation and alkoxycarbonylation of unactiavated aryl hydrazines. This protocol employs inert tertiary amines as an aminal source and arylhydrazines via oxidative sp3 and sp2 C−N bond...
