- A facile copper(i)-catalyzed homo-coupling of indanone derivatives using diaziridinone under mild conditions
-
A novel and efficient Cu(i)-catalyzed homo-coupling of indanone derivatives using diaziridinone as an oxidant is described. A variety of 1,4-dicarbonyl compounds bearing two adjacent quaternary stereocenters were obtained in high yields with high diastereoselectivities via a base-free and operationally simple process under mild reaction conditions.

- A dinuclear palladium catalyst for α-Hydroxylation of carbonyls with O2
-
A chemo- and regioselective α-hydroxylation reaction of carbonyl compounds with molecular oxygen as oxidant is reported. The hydroxylation reaction is catalyzed by a dinuclear Pd(II) complex, which functions as an oxygen transfer catalyst, reminiscent of an oxygenase. The development of this oxidation reaction was inspired by discovery and mechanism evaluation of previously unknown Pd(III)-Pd(III) complexes.
