解説フッ化セシウム (英: Cesium fluoride) とは、組成式CsFで表されるイオン化合物で、フッ化物イオンとセシウムイオンから成る無機化合物です。 CAS登録番号は、13400-13-0です。吸湿性のある物質ですが、減圧下で加熱することで容易に水分を除去することができます。フッ化物イオンの発生源として反応したり、塩基として用いられたりする物質です。フッ化セシウムは労働安全衛生法で名称等を表示・通知すべき有害物質に指定されている他、PRTR法で第一種指定化学物質に指定されています。

用途フッ化物イオンは求核性が低いので有機合成における有用な塩基である。クネーフェナーゲル縮合に用いた場合、フッ化カリウムやフッ化ナトリウムよりも良好な結果が得られる。

使用Used as a base in a Suzuki cross-coupling synthesis of ortho-substituted biaryls.5 Also employed as a reagent for nucleophilic fluorination of primary halides and sulfonates in protic media such as tert-butyl and tert-pentyl alcohols.6

使用Cesium fluoride is an inorganic compound with the chemical formula CsF, which is a hygmoscopic white salt. Cesium fluoride can be used as a source of fluoride anion for organic synthesis. Caesium has the highest electropositivity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.

一般的な説明Cesium fluoride is an inorganic compound known to be a source of fluoride ion and a catalyst in organic synthesis. It has been used in many organic reactions like 1,4elimination, desilylation, transesterification, acylation, nucleophilic aromatic substitution, etherification, crosscoupling reactions and so on.

使用用途フッ化セシウムは、化学分野において種々の反応に用いられる物質です。例えば、有機フッ素化学ではフッ素化物イオン源として利用され、有機合成においては求核性の低い有用な塩基として用いられます。また、フッ化セシウムは赤外線を透過する性質があるため、分析化学の分野では赤外分光法に利用されることがあります。赤外分光法とは、物体に赤外線を照射し、反射光や透過光をスペクトル分析する分析法のことです。フッ化セシウムは、赤外分光法において物体を挟む「窓板」という部分に用いられています。
