Substitution

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exc more

A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to "ion billiards." The new method could pave the way for creating numerous new materials, thus drastically advancing materials s more

Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have made a surpr more

Dioxygen complexes [Ru(η5-C5Me5)(η2-O2){P(OEt)3}2]BPh4 (1) and [Ru(η5-C5Me5)(η2-O2)(PPh3){P(OR)3}]BPh4 (2, 3) [R = Me (2), Et (3)] were prepared by allowing chloro-complexes RuCl(η5-C5Me5)[P(OEt)3]2 and RuCl(η5-C5Me5)(PPh3)[P(OR)3] to react with air (1 atm) in the presence of NaBPh4. Substitution of more

The reaction of [RhCl(CS)(PPh3)2] with excess catecholborane affords the cumulenic carbido complex [Rh2(μ-C)Cl2(PPh3)4] which undergoes phosphine and halide substitution to afford a range of complexes in which the Rh=C=Rh spine remains intact. Amongst these, the reactions with K[L] (L = H2B(pz)2, H2 more
