Preparation of bicyclo[4.2.0]octa-2,4-dien-7-one via trapping with benzylideneacetoneiron tricarbonyl
Abstract
The synthesis of bicyclo[4.2.0]octa-2,4-dien-7-one has been accomplished by trapping this unstable tautomer with benzylideneacetoneiron tricarbonyl to form the stable bicyclo[4.2.0]octa-2,4-dien-7-oneiron tricarbonyl which was then oxidatively cleaved with ceric ammonium nitrate at –30 °C to yield the title ketone.
