Supramolecular recognition for site-selective C-H oxidation

Site-selective C-H functionalization of aliphatic alkyl chains is a longstanding challenge in oxidation catalysis, given the comparable relative reactivity of the different methylenes. A supramolecular, bioinspired approach is described to address this challenge. A Mn complex able to catalyze C(sp3)-H hydroxylation with H2O2 is equipped with 18-benzocrown-6 ether receptors that bind ammonium substrates via hydrogen bonding.

Former IQCC member publishes in Nature

A few weeks ago for the first time an IQCC-related paper appeared in Nature, with the publication of “Discovery of a selective catalytic p300/CBP inhibitor that targets lineage-specific tumours”, with Maricel Torrent as one of the authors. Maricel defended her PhD thesis “On the mechanisms of Transition-Metal Catalyzed Model Reactions of Industrial and Synthetic Importance:

Chem. Comm. Cover on Chemical Reactivity of Endohedral HF@C60

A group of chemists from the Universidad Complutense de Madrid lead by Prof. Nazario Martín and from the University of Southampton lead by Prof. Richard J. Whitby together with the IQCC members Sílvia Osuna, Miquel Solà, and Marc Garcia-Borràs (ex-member of the IQCC, now in UCLA) have reported the first chemical modification on the endohedral

Highly reactive oxoiron(IV) with bioinspired N3O ligand

The sluggish oxidants, [FeIV(O)(TMC)(CH3CN)] 2+ (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) and [FeIV(O)(d12-TMCN)(OTf)] + (3d; d12-TMCN = 1,4,7,11-tetra-d3-methyl-1,4,7,11-tetraazacyclotetradecane), are transformed into a highly reactive oxidant, [FeIV(O)(TMCO)(OTf)] + (1; TMCO = 4,8,12-trimethyl-1-oxa-4,8,12-triazacyclotetradecane), upon replacement of a -NMe donor in the TMC and TMCN ligands by an O-atom. A rate enhancement of 5 – 6 orders of magnitude in both

Aryl-Co(III) Masked-Carbenes in Cobalt-Catalyzed C–H Functionalization

Herein we describe the synthesis of a family of aryl-Co(III)-carboxylate complexes and their reactivity with ethyl diazoacetate. Crystallographic, full spectroscopic characterization, and theoretical evidence of unique C-metalated aryl-Co(III) enolate intermediates is provided, unraveling a carboxylate-assisted formation of aryl-Co(III) masked-carbenes. Moreover, additional evidence for an unprecedented Co(III)-mediated intramolecular SN2-type C–C bond formation in which the carboxylate

Spin-state controlled photo-dissociation of Fe(III)-azide

We report the generation of iron(V) nitride complexes, which are targets of biomimetic chemistry. Temperature-dependent ion spectroscopy shows that this reaction is governed by the spin state population of their iron(III) azide precursors and can be tuned by temperature. The complex [(MePy2TACN)Fe(N3)]2+ exists as a mixture of sextet and doublet spin states at 300 K,
