An approach to regio- and stereo-controlled synthesis of 5,6-disubstituted cyclohexadiene derivatives via tricarbonyl[1–5-η-6-exo-(2-acetoxypropyl)cyclohexadienylium]iron tetrafluoroborate

Abstract

The title complex (3) has been prepared by a route involving oxidative cyclisation of (2) by thallium(III) trifluoroacetate; reaction of (3) with nucleophiles is regiospecific, stereospecific, and diastereoselective.
