일반 설명
Potassium carbonate is an inorganic base. It participates as base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene.
애플리케이션
Potassium carbonate was used in the following studies:
- Synthesis of polysubstituted iodobenzene derivatives.
- As base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.
- As base for the Suzuki coupling of aryl halides with aryl boronic acids.
- As base for the Heck reaction of styrene and bromobenzene.

The cobalt-catalyzed Diels-Alder reaction of trimethylsilyl-substituted alkynes with 1,3-dienes led to dihydroaromatic intermediates which were transformed into iodobenzene derivatives. For this transformation, the dihydroaromatic intermediates had to be oxidized and the trimethylsilyl-substituted arene had to undergo a silicon-iodine exchange reaction.
