With our compliments: The 1,3‐dicarbonyl unit has been shown to be a new and useful leaving group for iron‐catalyzed bond cleavage (see scheme). This new strategy can complement the traditional Friedel–Crafts reaction and was applied in the synthesis of indene derivatives.
An unprecedented protocol has been developed for the regioselectivesynthesis of structurally diverse indene derivatives from readily accessible N-benzylic sulfonamides and disubstituted alkynes through FeCl3-catalyzed cleavage of sp3 carbon−nitrogen bonds to generate benzyl cation intermediates. In the presence of 10 mol % of FeCl3, a broad range of N-benzylic sulfonamides smoothly react with internal
