Synthesis of trifluoroacetyl iodide (TFAI) from trifluoroacetyl chloride (TFAC) and hydrogen iodide (HI) in liquid phase reaction

The present disclosure provides a process for the preparation of trifluoroacetyl iodide (TFAI) in a liquid phase reaction. Specifically, the present disclosure provides a liquid phase reaction of trifluoroacetyl chloride (TFAC) and hydrogen iodide (HI) with or without a catalyst to form trifluoroacetyl iodide (TFAI). The reaction may be carried out at ambient or elevated temperatures. 本公开提供了一种用于在液相反应中制备三氟乙酰碘(TFAI)的方法。具体地，本公开提供了在具有或不具有催化剂的情况下三氟乙酰氯(TFAC)和碘化氢(HI)的液相反应，以形成三氟乙酰碘(TFAI)。该反应可在环境温度下或升高的温度下进行。
