ABSTRACT
This chapter discusses the bene’ts of microwave heating over traditional thermal heating, both to the environment and to pedagogy in the organic chemistry laboratory. It is written as a practical guide for educators who may wish to transition to microwave technology, from the perspective of an organic chemistry instructor of undergraduates. The speci’cs of microwave ovens suitable for the undergraduate laboratory are described, without making a detailed comparison of commercially available ovens and accessories. A foundation is provided in microwave techniques, and the physics of microwave-matter interaction that generates reaction rate enhancements. Also included is a brief history outlining the development of microwave technology, and what quali’es it as a “greener” heating strategy. It is not intended as a comprehensive review of all microwave-accelerated reactions, but transformations that have proven useful for the organic laboratory are highlighted. The chapter offers answers to the following ’ve important questions: (1) What chemistry will most likely undergo microwave rate acceleration? (2) Which type of microwave oven should one buy? (3) How much will an oven cost? (4) Which solvents should be tried? (5) What “cook” temperatures and heating periods are appropriate?
