Angewandte Chemie International Edition by Fanzhi Yang, Karsten Rauch, Katharina Kettelhoit, Lutz Ackermann / 2h // keep unread // hide // preview Abstract Versatile ruthenium(II) complexes allow for site-selective CH oxygenations with weakly-coordinating aldehydes. The challenging CH functionalizations proceed with high chemoselectivity by rate-determining CH metalation. The new method features an ample substrate scope, which sets the stage for the step-economical preparation of various bioactive heterocycles. The weakest link : Challenging aryl CH oxygenations with very weakly coordinating aldehydes proceed chemoselectively in the presence of versatile ruthenium(II) catalysts under mild reaction conditions. This transformation features an ample substrate scope and excellent positional selectivity. Visit Website

Back Cover: Oxygenation by Ruthenium Monosubstituted Polyoxotungstates in Aqueous Solution: Experimental and Computational Dissection of a Ru(III)–Ru(V) Catalytic Cycle (Chem. Eur. J. 35/2014)
おもしろいカバーです。それだけですが。 Chemistry - A European Journal by Andrea Sartorel, Pere Miró, Mauro Carraro, Serena Berardi, Olga Bortolini, Alessandro Bagno, Carles Bo , Marcella Bonchio / 11h // keep unread // hide // preview Polyoxometalate ligands play a key role in facilitating a ruthenium catalyst access to a high-valent reactive state in aerobic oxidation in water. In their Full Paper on page 10932 ff. , C. Bo, M. Bonchio et al. show that the reaction involves novel ruthenium–peroxo and oxene intermediates embedded within a totally inorganic POM environment. This breakthrough perspective is one the central themes of the European COST action entitled Polyoxometalate Chemistry for Molecular Nanoscience (PoCheMoN). The cover art is inspired by the popular fantasy game (Pokémon).
Iron(III) complexes of tripodal tetradentate 4N ligands as functional models for catechol dioxygenases: the electronic vs. steric effect on extradiol cleavage
RSC - Dalton Trans. latest articles by Mani Balamurugan Dalton Trans. , 2014, Advance Article DOI : 10.1039/C3DT52145A, Paper Mani Balamurugan, Prabha Vadivelu, Mallayan Palaniandavar The extradiol ( E ) to intradiol ( I ) product selectivity ( E / I , 0.1-2.0) depends upon the asymmetry in bidentate coordination of catecholate, as determined by the stereoelectronic properties of the ligands.

ABSTRACT EDITOR'S SUMMARY The photosynthetic protein complex photosystem II oxidizes water to molecular oxygen at an embedded tetramanganese-calcium cluster. Resolving the geometric and electronic structure of this cluster in its highest metastable catalytic state (designated S 3 ) is a prerequisite for understanding the mechanism of O-O bond formation. Here, multifrequency, multidimensional magnetic resonance spectr...
