一般描述
碳酸钾是一种无机碱。它可作为碱参与环钯配合物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
碳酸钾已用于制备双磺化双[4-(3-氨基苯氧基)苯基]砜，一种双磺化二胺单体。
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。
- 作为各种双酚类高分子量均聚物和共聚物合成反应所需碱。
- 作为芳基卤和芳基硼酸的Suzuki偶联反应所需碱。
- 苯乙烯和溴苯的Heck反应。
特点和优势
- 提高效率——免除需要松散硬化粉末的时间和精力
- 更加安全——避免使用工具大力敲碎团块的风险
- 更加经济——制备和溶剂化速度更快，提高效率并节约成本
- 质量保证——经过专业检测的出色品质，无抗结剂添加
- 灵活的用量选择——有从研究到放大级别的用量规格可供选择

Several methods to synthesize poly(phenylene) block copolymers through the nickel coupling reaction were attempted to reduce the use of expensive nickel catalysts in polymerization. The model reaction for poly(phenylene) having different types of dichlorobenzene derivative monomers illustrated the potential use

Fluorine-18 labeled radiotracers, such as [(18)F]fluorodeoxyglucose, can be used as practical diagnostic agents in positron emission tomography (PET). Furthermore, the properties of pharmaceuticals can be enhanced significantly by the introduction of fluorine groups into their original structures, and significant progress

In the insulin resistant heart, energy fuel selection shifts away from glucose utilization towards almost complete dependence on long-chain fatty acids (LCFA). This shift results in excessive cardiac lipid accumulation and eventually heart failure. Lipid-induced cardiomyopathy may be averted by

We have measured the single-molecule conductance of a family of oligothiophenes comprising 1-6 thiophene moieties terminated with methyl-sulfide linkers using the scanning tunneling microscope-based break-junction technique. We find an anomalous behavior: the peak of the conductance histogram distribution does not
