Hypoiodite-catalysed oxidative homocoupling of arenols and tandem oxidation/cross-coupling of hydroquinones with arenes

A transition-metal-free method for the oxidative C–C homocoupling and tandem oxidation/cross-coupling is reported.

Discovery and mechanistic investigation of Pt-catalyzed oxidative homocoupling of benzene with PhI(OAc)2

Pt-catalyzed direct coupling of benzene to biphenyl using PhI(OAc)2 as an oxidant in the absence of any acid as a co-solvent or co-catalyst was mechanistically investigated.

Palladium-catalyzed oxidative homocoupling of pyrazole boronic esters to access versatile bipyrazoles and the flexible metal–organic framework Co(4,4′-bipyrazolate)

A facile catalytic protocol achieves the homocoupling of pyrazole boronic esters, enabling access to the structurally-flexible metal–organic framework Co(bpz).
