Green chemistry: solventless as a new approach for a greener organic chemical reactions.

Includes references.

The term “green chemistry,” describes an area of research and chemical practice that arises from scientific discoveries about pollution and ecological interdependence. Green chemistry is not necessarily environmental chemistry, although it may involve some of this. It is chemistry for the environment. Green chemistry tries to avoid pollution by utilizing green processes. One of the twelve principles of green chemistry asks us to: ‘use safer solvents and auxiliaries’. The expansion of solvent-free organic synthetic methods has thus become an important and popular research area. Reports on solvent-free reactions between solids, between gases and solids, between solids and liquid, between liquids, and on solid inorganic supports have become increasingly frequent in recent years. The avoiding of organic solvents in organic syntheses is a most important goal in green chemistry. Solvent-free organic reactions make syntheses much simpler, save energy, and prevent solvent wastes, hazards, and toxicity.
