hemistry is the science about breaking and forming of bonds between
atoms. One of the most important processes for organic chemistry is
breaking bonds C-H, as well as C-C in various compounds, and
primarily, in hydrocarbons. Among hydrocarbons, saturated
hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are
especially attractive as substrates for chemical transformations.
This is because, on the one hand, alkanes are the main constituents
of oil and natural gas, and consequently are the principal
feedstocks for chemical industry. On the other hand, these
substances are known to be the less reactive organic compounds.
Saturated hydrocarbons may be called the "noble gases of organic
chemistry" and, if so, the first representative of their family -
methane - may be compared with extremely inert helium. As in all
comparisons, this parallel between noble gases and alkanes is not
fully accurate. Indeed the transformations of alkanes, including
methane, have been known for a long time. These reactions involve
the interaction with molecular oxygen from air (burning - the main
source of energy!), as well as some mutual interconversions of
saturated and unsaturated hydrocarbons. However, all these
transformations occur at elevated temperatures (higher than 300-500
DegreesC) and are usually characterized by a lack of selectivity.
The conversion of alkanes into carbon dioxide and water during
burning is an extremely valuable process - but not from a chemist
viewpoint.
