Silver promoted electrocyclic ring opening

Bromo-l-aryl-substituted indenes have been reported to be synthesized from 1,2-diaryl-substituted gem-dibromocyclopropanes via a domino sequence involving silver(I)-promoted ionization and 2a -disrotatory electrocyclic ring-opening followed by a 4a -conrotatory electrocyclic ring-closing reaction of the allylic carbocation intermediate (Scheme 46). ... [Pg.535]
