accelerates the Ir-catalyzed C−H borylation of aromatic substrates when compared with reactions carried out at the same temperature under standard heating conditions. Application to a one-pot single solvent process for tandem C−H borylation/Suzuki−Miyauracross-coupling sequences using microwave-accelerated reactions gives fast and efficient access to a wide range of biaryl and heterobiaryl compounds.
Mild, novel procedures have been developed for the syntheses of arylhalides from the correspondingphenols in modest to good yields via boronate ester intermediates.

Nano-Fe2O3-catalyzed borylation of arenes with diboron pinacol ester B2pin2 has been found to give borylation products with selectivity controlled by electronic effects of substituents.

In this study, C(sp2)–Hborylation of arenes was accomplished by a nickel catalyst, resulting in good yield. Alkyl and alkoxy arenes were successfully functionalized, affording C(sp2)–H borylated compounds. It was unraveled that the well-defined abnormal N-heterocyclic carbene based Ni(II) complex breaks into Ni nanoparticles (Ni-NPs), which act as catalytically active species. A series of controlled
