The invention belongs to the technical field of the chemical synthesis, and particularly relates to a method for efficiently preparing a sulfuryl fluorides compound by catalytic fluorination. The provided method for efficiently preparing the sulfuryl fluorides compound by the catalytic fluorination comprises the following steps: enabling a sulfonyl chlorides compound to react with a hydroge fluoride under the action of a catalyst of a sulfonic acids derivative, to obtain the sulfuryl fluorides compound. A novel catalytic technology is provided, and the method has extensive substrate applicability. Efficient catalytic efficiency and yield are expressed.

Various carboxylic acids were converted into acyl fluorides in excellent yields by treatment with trichloroacetonitrile, triphenylphosphine, and TBAF(t-BuOH)4 at room temperature. The reaction was applicable to the preparation of acid-sensitive amino acid fluorides without deprotection or rearrangement
