Copper-Mediated Cross-Coupling of H-Phosphonates with Vinyliodonium Salts:
Novel Very Mild Synthesis of 2-Arylvinylphosphonates. — A new very mild re27- 169 A
action between readily available vinyliodonium tetrafluoroborates and H-phosphonates
proceeds well at room temperature to afford the coupling products in good yields. In
some cases, slow syringe-pump addition of the reagents is crucial for the success. The
broad scope is proved by application to the preparation of arabino-furanosyl derivatives
(XI) and more complex structures (XIII). — (THIELGES, S.; BISSERET*, P.;
