, p. 995 - 1001 (2016)
Isomerization reactions of cyclooctyne mediated by N-heterocyclic carbene supported gold(I) leading to ring-contraction and the formation of 5/5-fused bicyclic alkenes have been observed. Isolation and complete characterization, including X-ray structural data of the cationic gold(I) complexes featuring the precursor alkyne and the product alkenes are also described. Gold catalyzes the isomerization of cyclooctyne leading to alkenes featuring two fused five-membered rings.
Oxidative C(sp3)-H bond cleavage, C-C and CC coupling at a boron center with O2 as the oxidant mediated by platinum(II)

Dimethyl- and diphenylplatinum(II) fragments PtIIR2 (R = Me, Ph) enable facile and efficient oxidative C(sp3)-H bond cleavage and stepwise C-C and C=C coupling at the boron atom of a coordinated 1,5-cyclooctanediyldi(2-pyridyl)borato ligand with O2 as the sole oxidant. the Partner Organisations 2014.
