Description:

This chapter gives a brief introduction about solvent-free reactions whose importance can be gauged by the increasing number of publications every year during the last decade. The mechanistic aspects of the reactions under solvent-free conditions have been highlighted. Our observation reveals that the use of alternate energy input, such as microwave, ultrasound, and mechanical grinding are better suited for the solvent-free reaction over conventional heating. However, the solvent-free asymmetric reactions provide better enantiomeric excess if they were performed at ambient condition or below room temperature.
