一般描述
碳酸钾是一种无机碱。作为碱参与 palladacycle 催化的氯苯与苯乙烯的 Heck 反应。向 K2CO3（溶剂）中加入氨基酸（甘氨酸、肌氨酸和脯氨酸）可促进 CO2 的吸收。
应用
碳酸钾被用于制备双磺化双（4-（3-氨基苯氧基）苯基）砜（一种二磺化二胺单体）。
它可用于以下研究：
它可用于以下研究：
- 作为合成多取代碘苯衍生物的试剂。

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.
