Fluorous synthesis of allylic fluorides: C-F bond formation as the detagging process

Boldon, Sophie,Moore, Jane E.,Gouverneur, Veronique

, p. 3622 - 3624 (2008)

A novel fluorous tagging-detagging strategy has been developed featuring a fluorination as the detagging process; fluorous allylsilanes were prepared by cross-metathesis and subsequently subjected to electrophilic fluorodesilylation; Selectfluor was used as the detagging reagent; the resulting allylic fluorides were successfully purified by fluorous solid phase extraction.
