Abstract

A convenient CsF-promoted iodocyclization reaction of trisubstituted allenylphosphonates with iodine to construct highly functionalized oxaphospholene derivatives has been developed. A series of readily available starting materials including ferrocenylallenes, aromatic and alkyl substituted allenes can undergo the process successfully.
