Nonthermal Effects of Microwaves in Organic Synthesis

The main results are compiled in exhaustive reviews [3-7] and books [8-11]. Most of these publications describe important acceleration for a wide range of organic reactions, especially when conducted under solvent-free conditions. The combination of solvent-free reaction conditions and microwave irradiation leads to large reductions in reaction times, enhancements in conversions, and, sometimes [4, 12], in selectivity with several advantages of the eco-friendly approach, termed Green Chemistry . [Pg.134]

In this range of frequency, the charge space polarization [22, 23, 27] can also intervene and can be of prime importance with semiconductors, because it concerns materials which contain free conduction electrons. This phenomenon is essential in the heating of more or less magnetic solid particles, for example a variety of mineral oxides or metallic species. [Pg.136]

The acceleration of reactions by microwave exposure results from material-wave interactions leading to thermal effects (which may be easily estimated by temperature measurement) and specific (not purely thermal) effects. Clearly, a combination of these two contributions can be responsible for the observed effect, discussed in [Pg.136]
