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