Herein, we report a new tripodal tris-benzimidazole ligand (Tbim) that structurally mimics the 3-His coordination environment of certain nonheme mononuclear iron oxygenases. The coordination chemistry of Tbim was explored with iron(II) revealing a diverse set of coordination modes. The aerobic oxidation of biomimetic model substrate diethyl-2-phenylmalonate was studied using the Tbim?Fe and Fe(OTf)2.

To support mechanistic inferences made for an iron-based dioxygenase model, a nickel analogue, i.e. a TpNi-malonate (1) was prepared. 1 proved to represent a rare case of a nickel complex reacting with O2 in a controlled manner-mechanistically different from the iron case-and leads to hydroxylation of the malonate.
I2-catalyzed direct α-hydroxylation of β-dicarbonyl compounds with atmospheric oxygen under photoirradiation

An I2-catalyzed hydroxylation of β-dicarbonyl moieties using air as the oxidant under photoirradiation has been developed for the easy preparation of α-hydroxy-β-dicarbonyl compounds. The transformation was completed with only 1 mol % of I2. With α-unsubstituted malonates, the hydroxylated dimerization product was afforded as the predominant product along with a minor product, α,α-dihydroxyl malonate.

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.

Monguchi, Yasunari,Takahashi, Tohru,Iida, Yusuke,Fujiwara, Yuta,Inagaki, Yuya,Maegawa, Tomohiro,Sajiki, Hironao

A hydroxyl group was readily and directly introduced into the α-position of a variety of β-dicarbonyl compounds by heterogeneous Pd/C-catalyzed oxygenation using molecular oxygen. Georg Thieme Verlag Stuttgart.
