Microwave Synthesis - Organic Chemistry

The discussion on the use of microwave units specially designed for synthesis use, which are often quite expensive, becomes rather heated at times. Unmodified home microwave units are suitable in some cases. However, simple modifications (for example, a reflux condenser) can heighten the safety factor.

Microwave assisted synthesis: A green chemistry approach

2018-9-19  Microwave synthesis is an important technique for facilitating drug discovery, polymer science, chemical and materials research.
