Oxidative activation of the catalyst to nanoITO-Ru IV (OH) 3+  induces oxidation of MTO. The reaction is first ord

Wang  /   22d   //   keep unread   //   hide   //   preview Abstract Crown ethers are small, cyclic polyethers that have found wide-spread use in phase-transfer catalysis and, to a certain degree, in protein chemistry. Crown ethers readily bind metallic and organic cations, including positively charged amino acid side chains. We elucidated the crystal structures of several protein-crown ether co-crystals grown in the presence of 18-crown-6. We then employed biophysical methods and molecular dynamics simulations to compare these complexes with the corresponding apoproteins and with similar complexes with ring-shaped low-molecular-weight polyethylene glycols. Our studies show that crown ethers can modify protein surface behavior dramatically by stabilizing either int

In the presence of [Ru(bpy) 3 ] 2+  and S 2 O 8 2− , photoinduced oxygen evolution can be observed with a turnover frequency (TOF) of 1.4±0.1 mol(O 2 ) mol( 1 ) −1  s −1  and a maximal turnover number (TON) of 58±5 mol(O 2 ) mol( 1 ) −1 . The complex is shown to act as a molecular and homogeneous catalyst and a mechanism is proposed based on the combination of EPR data and light-driven O 2  evolution kinetics. Light-driven oxygen evolution:  A dinuclear cobalt complex has been synthesized as a molecular and homogeneous catalyst for light-driven and electrochemical water oxidation. The catalyst can efficiently promote oxygen evolution under visible-light irrad

Angewandte Chemie International Edition  by Abraham B. Alemayehu, Kevin J. Gagnon, James Terner, Abhik Ghosh  /   1h   //  keep unread   //   hide   //   preview Abstract Heavy-element corroles are of great interest as optical sensors, near-IR dyes, phosphors, organic light-emitting diodes, and anticancer compounds. Insertion of 5d metals into corroles, however, is often a difficult and unpredictable process. Against this backdrop, oxidative metalation of meso triarylcorroles with [Os 3 (CO) 12 ]/NaN 3  in refluxing 1:2 diethylene glycol monomethyl ether/glycol has provided a convenient and relatively high-yielding route to nitridoosmium(VI) corroles, three of which could be characterized with single-crystal X-ray structure analysis. Last man standing!  After the synthesis of platinum corroles, osmium was the last remaining middle and late 5d metal to be inserted into the contracted porphyrin analogue. Oxidative metalation has now provided a moderately high

Angewandte Chemie International Edition  by Michael K. Coggins, Ming-Tian Zhang, Zuofeng Chen, Na Song, Thomas J. Meyer  /   18d   //   keep unread   //   hide   //   preview Abstract The complex Cu II (Py 3 P) ( 1 ) is an electrocatalyst for water oxidation to dioxygen in H 2 PO 4 − /HPO 4 2−  buffered aqueous solutions. Controlled potential electrolysis experiments with  1  at pH 8.0 at an applied potential of 1.40 V versus the normal hydrogen electrode resulted in the formation of dioxygen (84 % Faradaic yield) through multiple catalyst turnovers with minimal catalyst deactivation. The results of an electrochemical kinetics study point to a single-site mechanism for water oxidation catalysis with involvement of phosphate buffer anions either through atom–proton transfer in a rate-limiting OO bond-forming step with HPO 4 2−  as the acceptor base or by concerted electron–proton transfer with electron transfer to the electrode and proton transfer to the HPO 4 2−  base.
