Abstract
A Pd-catalyzed domino carbopalladation/C–H-activation reaction of phenoxyphenyl-substituted propargylic alcohols was used for the synthesis of tetrasubstituted alkenes bearing either a dihydroindene or benzo[7]annulene motif. These compounds are of interest for the construction of molecular switches and motors.
