General description

Potassium carbonate is an inorganic base.[1] It participates as base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene.[2]

Application

Potassium carbonate was used in the following studies:
  • Synthesis of polysubstituted iodobenzene derivatives.[3]
  • As base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.[4]
  • As base for the Suzuki coupling of aryl halides with aryl boronic acids.[5]
  • As base for the Heck reaction of styrene and bromobenzene.[1]

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.

ortho-Arylation of ortho-substituted benzoic acids is a challenging process due to the tendency of the reaction products toward Pd-catalyzed protodecarboxylation. A simple method for preventing decarboxylation in sterically hindered benzoic acids is reported. The method described represents a reliable and
