Two types of mathematical relations are discussed, which represent the connection between carbon-carbon bond energies and carbon-carbon bond distances. They similarly describe the relation between carbon-hydrogen bond energies and the corresponding carbon-hydrogen bond distances....

Single bonds between carbon atoms maximize the hydrogen content in hydrocarbons, and are referred to as ‘saturated’. A common hydrogen application is the hydrogenation of unsaturated animal fats and oils. The conversion of these unsaturated compounds to saturated compounds increases their melting point...

Facile alkane functionalization by means of the insertion of :CHCO2Et, from ethyl diazoacetate, into carbon−hydrogen bonds mediated by catalytic amounts of (NHC)MCl (NHC = N-heterocyclic ligand; M = Cu, Au) and a halide scavenger MX has been achieved. This chemistry includes the insertion...
