Inden-2-one and some simple derivatives are smoothly generated by
reaction of caesium fluoride with
1-bromo-2-tert-butyldimethylsilyloxyindenes and they can be
efficiently trapped in both intra- and inter-molecular additions; the
intramolecular additions proceed with exo-addition of the tether,
in contrast to the intermolecular additions and intramolecular additions
to 2-benzopyran-3-ones.
