چکیده

This paper mainly described the new instruments of microwave-promoted organic synthesis which were appraised, and several microwave-assisted synthetic reactions, such as esterification reaction, orthogonal experimental design and fentanyl synthetic reactions. In comparison with traditional methods of organic synthesis, microwave-assisted chemistry could make high-speed processing of chemical transformation, to ensure short reactions times and allow for an optional-reproducibility, optimization process, optional power levels and the other optional reaction conditions. Our ongoing research work may lay foundation on investigating the mechanism of microwave-promoted organic synthetic reactions.
