Electronic and steric arguments as well as experimental evidence are presented to prove that the hydrogen bond is at carbon. Proof is given for a carbon-hydrogen-carbon bond between an isocyanide and the C-H in an acetylene. Frequency shift and equilibrium data indicate that isocyanides (carbon...
Direct carbon–hydrogen bond functionalization has attracted considerable attention and plays a key role in organic transformations. Currently, copper is showing great potential as a catalyst in C–H bond-functionalization reactions because of its low cost and unique reactivity. This review summarizes the...

Methods for carbon–hydrogen (C–H) bond oxidation have a fundamental role in synthetic organic chemistry, providing functionality that is required in the final target molecule or facilitating subsequent chemical transformations. Several approaches to oxidizing aliphatic C–H bonds have been described, dr...
which may undergo strain release of the palladacycle and Pd insertion into the aliphatic carbon–hydrogen bond. Inspired by recent successes in the use of ligands to promote efficiency27, accelerate the rate28, and even control stereoselectivity in carbon–hydrogen activations29,30, we envisaged that...

In this state, the adsorbed hydrogen tends to penetrate into the volume. In the other antisymmetry state /sup 2/A'', the hydrogen has a bridge bond (the B/sub 2/ state). The calculations predict that in this state the strength of the bond between hydrogen and the surface is greater ...
There is a need to understand the hydrogen sorption mechanism(s). In this work, hydrogenated graphite samples were characterized by TGA-Mass Spectrometry, Raman spectroscopy and high resolution TEM. It was found that graphite milled for various times (0-40 h) had different d-spacings and CHx ...
