Abstract Herein, we report a copper salt‐controlled divergent reactivity toward α‐diazocarbonyl compounds. By simple change of the counteranion under identical reaction conditions, reported method allowed an easy access to either ( Z )‐α‐fluorovinylphosphonate or alkyl‐SCF 2 PO(OEt) derivatives in good yields. Mechanistic studies were performed and suggested two different pathways explain formation these products.
