This work was supported by the National Natural Science Foundation of China (21662025), National College Student Innovation and Entrepreneurship Training Program (202014532005, 202114532003, 202114532009), Ordos Institute of Technology Project (KYYB2020007).
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.
