“…Recent interest in the characterization of potential Au III intermediates has resulted in the isolation of both an Au III hydride36 and an Au III vinyl37 complex. Herein, we describe the preparation of the first crystallographically characterized Au III alkene complex and discuss the factors that contribute to the stability of this unusual molecule, in which the Au center is directly bonded solely to carbon atoms.…”

International audienceA Missing Gold Link: An Au(III) alkene complex has been prepared and characterized by NMR spectroscopy and X-ray crystallography. Its bonding features have been analyzed by DFT calculations and natural bond orbital (NBO) analysis. In [(cod)AuMe(2) ](+) , the unequal AuC bond lengths result from the domination of the preference of 1,5-cyclooctadiene (cod) for nonparallel double bonds over back donation from the metal which favors parallel double bonds

“…Now, Bochmann and co‐workers have reported the synthesis of a stable gold(III) monohydride 3 21 bearing a C‐N‐C pincer ligand. The gold hydroxide 2 22 was treated with LiHBEt 3 in toluene at −78 °C and subsequent stirring of the reaction mixture at room temperature for 15 min provided 3 as a dark yellow crystalline complex in 75 % yield.…”

A new family of artificial transcription factor (ATF)-based conjugates have been designed and synthesized as potent chemical nucleases. Polyamides as the important and efficient ATFs were used to modify and activate several anchor compounds. The results demonstrate that the resulting conjugates remarkably promote the rate accelerations and non-random double-strand DNA cleavage activity. Interestingly, the cleavage activity of both the hydrolytic and oxidative agents was promoted efficiently through the modification of the ATFs.

“…Die Arbeitsgruppe von Bochmann beschrieb erstmals ein thermisch stabiles Gold(III)‐Hydrid [LAuIIIH] mit einem doppelt cyclometallierten Pinzettenliganden (L = 2,6‐Bis(4'‐tert‐butylphenyl)pyridin‐Dianion) 1. Der Komplex wurde durch die Umsetzung des Hydroxids [LAuOH] mit dem Superhydrid LiBHEt3 synthetisiert (Abbildung 1a).…”

This study aims to examine the efficiency of Opuntia ficus‐indica for removing organochlorine pesticides from surface waters. Adsorption properties such as size, dose, and time of O. ficus‐indica for aldrin, dieldrin, and dichlorodiphenyltrichloroethane (DDT) were studied through stirring and column methods. Because of their high affinity and swelling characteristics, dried O. ficus‐indica was studied in stirring while fresh unpeeled O. ficus‐indica was applied in both stirring and column experiments and proved to be well‐suited to column application. Before removing pesticides, the column was flashed with distilled water eliminate the turbidity and smell from fresh unpeeled cactus. The removal of pesticides increased with an increasing adsorbent dose and decreased with adsorbent particle sizes. The optimum adsorbent dose is 10 g for dried and 15 g for fresh unpeeled O. ficus‐indica. The experimental results show that O. ficus‐indica possesses strong adsorption ability for aldrin, dieldrin, and DDT, and the adsorption isotherm data obeyed the Freundlich model. The results of our small‐scale experiments suggest a strong potential to develop local small‐scale water treatment units that can be used at the level of individual households or local communities, using a widely available adsorbent.
