Carboxamidate Ligand Noninnocence in Proton Coupled Electron Transfer
(2019)Recent breakthroughs have brought into question the innocence (or not) of carboxamidate donor ligands in the reactivity of high-valent oxidants. To test the reactivity properties of high-valent carboxamidate complexes, ... -
Investigating the Impact of Conformational Molecular Engineering on the Crystal Packing of Cavity Forming Porphyrins
(2019)Herein we report the synthesis of 5,10,15,20-tetraaryl-(X)-substituted- 2,3,7,8,12,13,17,18-octaethylporphyrins (OETArXPs) and a structural investigation of their solid-state properties via small molecule X-ray diffraction. ... -
Mimicking Class Ib Mn2 -Ribonucleotide Reductase: A MnII2 Complex and Its Reaction with Superoxide
(2018)A fascinating discovery in the chemistry of ribonucleotide reductases (RNRs) has been the identification of a dimanganese (Mn2 ) active site in class I b RNRs that requires superoxide anion (O2.- ), rather than dioxygen ... -
Perfluorinated phosphine and hybrid P-O ligands for Pd catalysed C-C bond forming reactions in solution and on Teflon supports
(2019)The synthesis of two types of phosphine ligands that feature perfluorinated ponytails is reported. A bidentate (RfCH2CH2)2PCH2CH2P(CH2CH2Rf)2 (Rf = CF3(CF2)n; n = 5, 7) and an alkoxyphosphine made by ring opening a fluorous ... -
Preparation and Characterisation of a Bis‐μ‐Hydroxo‐NiIII2 Complex
(2019)Hydroxide‐bridged high‐valent oxidants have been implicated as the active oxidants in methane monooxygenases and other oxidases that employ bimetallic clusters in their active site. To understand the properties of such ...
