Metal-Free Dihydrogen Oxidation by a Borenium Cation:A Combined Electrochemical/Frustrated Lewis Pair Approach [PDF]
, 2014 In order to use H2 as a clean source of electricity, prohibitively rare and expensive precious metal electrocatalysts, such as Pt, are often used to overcome the large oxidative voltage required to convert H2 into 2 H+ and 2 e−. Herein, we report a metal-

N-Heterocyclic carbene-stabilised arsinidene (AsH) [PDF]
Chemical Communications, 2017 N-Heterocyclic carbene adducts of the parent arsinidene (AsH) were prepared by two different synthetic routes, either by reaction of As(SiMe3)3 with 2,2-difluoroimidazolines followed by desilylation or by reaction of [Na(dioxane)3.31][AsCO] with imidazolium chlorides.

Copper(I) carbene hydride complexes acting both as reducing agent and precursor for Cu ALD: a study through density functional theory [PDF]
, 2015 We propose dual functional copper complexes that may act both as reducing agents and as Cu sources for prospective Cu atomic layer deposition. The example here is a CuH carbene complex, which can donate the H− anion to another Cu precursor forming ...
