Abstract: Oxidative dehydrogenation of 2-bromo-4-methylaniline with manganese(iv) oxide leads to the formation of (E)-1,2-bis(2-bromo-4-methylphenyl)diazene (1). The reaction of 1 with hydrazine hydrate gives the reduction product, 1,2-bis(2-bromo-4-methylphenyl)hydrazine (2). Compound 2 sequentially treated with methyllithium and two… read more here.

DOI: 10.1021/acs.orglett.2c00073
Abstract: An attractive palladium-catalyzed three-component reaction of ortho-amino aryl diazo esters, allyl carboxylates, and carbon monoxide (CO) has been developed. This catalytic system rendered domino carbene migratory insertion and carbonylation. Remarkably, 2-indolones 3 with a C3… read more here.

DOI: 10.1039/c6ra25501a
Abstract: In spite of their widespread use as catalysts, 1,2,3,4,5-pentamethylcyclopentadienyl (Cp*) iridium complexes have been rarely employed in the synthesis of pyridine derivatives. Herein, we used density functional theory (DFT) calculations to predict the [Cp*Ir(OAc)]+-catalysed synthesis… read more here.
