A method for preparing cyano sulfonyl fluoride compounds is provided. Oxime ether compounds are used as free radical precursors, and under the condition of photocatalyst regulation, and in combination with the strategy of free radical sulfur dioxide insertion, the process involves photocatalytic oxidation, CC bond cleavage rings, free radical SO.sub.2 insertion and fluorination to achieve cyano/fluorosulfonyl reaction of oxime ether, yielding cyano sulfonyl fluoride products.
