AI Article Synopsis

  • Researchers discovered that changing the copper salt used in reactions with α-diazocarbonyl compounds can significantly alter the outcome of the reaction.
  • This method allows for the efficient production of two different types of compounds—(Z)-α-fluorovinylphosphonate and alkyl-SCF PO(OEt) derivatives—just by altering the copper counteranion.
  • Mechanistic studies indicate that two distinct paths are involved in the formation of these products, helping to explain the different reactivities observed.

Article Abstract

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.
