Microwave-assisted polymer chemistry: Heck-reaction,transesterification, Baeyer–Villiger oxidation, oxazoline polymerization, acrylamides, and porous materials

Abstract—Several questions are still open concerning the different effects of microwave (MW) irradiation in organic and macromolecular chemistry. Analyzing experimental results on a relatively broad investigation area, we came to elucidate three main effects of microwave irradiation: efficient non-contact heating, an accelerating effect, and what we term a special effect.
In this paper, we report the first MW assisted synthesis of poly (2, 5-dibutoxy-1, 4-phenylenevinylene) via Heck-polycondensation as an example for efficient heating. The facile synthesis of the higher lactones 1-oxa-2-oxocyclooctanone and 1-oxa-2-oxocyclononanone via Baeyer–Villiger reaction offers indeed an example for theMW-accelerating effect. A survey of our recent work is also given to explain the effects more in detail and to provide examples of the special MWeffect.
