Method for efficiently preparing sulfuryl fluorides compound by catalytic fluorination

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.
