The system has been designed to mimic catalytic intermediates of the tungstoenzyme acetylene hydratase. The thiophenyl- oxazoline ligand S-Phoz (2-(4 ’ ,4 ’ -dimethyloxazolin-2 ’ -yl)thio- phenolate) is used to generate a bioinspired donor environment around the Wcenter, facilitating the stabilization of W– acetylene adducts. The featured complexes [W(C 2 H 2 )(CO)(S- Phoz) 2 ] ( 2 ) and [WO(C ...

One-step selective benzene hydroxylation is an attractive yet challenging method for phenol production, especially when such a reaction can be driven by solar energy. Herein, we reported that a highly selective benzene hydroxylation to phenol can be achieved over two Fe-based metal–organic frameworks [MIL-100(Fe) and MIL-68(Fe)] under visible light irradiations using hydrogen peroxide (H 2 O 2 ) as an oxidant. An optimal benzene conversion of 30.6% was...

This complex was found to mediate the hydrosilylation of 17 different aldehydes and ketones under mild conditions. When low loadings were employed in the absence of solvent, hydrosilylation turnover frequencies as high as 2475 min −1  were achieved. Comparison to leadi...

Naomi Levy, Atif Mahammed, Monica Kosa, Dan T. Major, Zeev Gross,* and Lior Elbaz*  Angewandte Chemie International Edition Angew. Chem. Int. Ed. 2015 , 54 , 1 – 6 Article first published online: 2 OCT 2015 DOI: 10.1002/anie.201505236 http://onlinelibrary.wiley.com/doi/10.1002/anie.201505236/abstract  Abstract The future of affordable fuel cells strongly relies on the design of earth-abundant (non-platinum) catalysts for the electrochemical oxygen reduction reaction (ORR). However, the bottleneck in the overall process occurs therein. We have examined herein trivalent Mn, Fe, Co, Ni, and Cu complexes of β-pyrrole-brominated corrole as ORR catalysts. The adsorption of these complexes on a high-surface-area carbon powder (BP2000) created a unique composite material, used for electrochemical measurements in acidic aqueous solutions. These experiments disclosed a clear dependence of the catalytic activity on the metal c...

Recently, nickel catalysis has been shown to participate in a wide variety of C−C bond-forming reactions, most notably Negishi, Suzuki – Miyaura, Stille, Kumada and Hiyama couplings 1 ,  2 . Despite the tremendous advances in C−C fragment couplings, the ability to forge C−O bonds in a general fashion via nickel cataly...
