RADICAL CYCLISATION OF 1-BROMO-2-(PROP-2-ENYLOXY)BENZENE USING A POLYMER-SUPPORTED ORGANOTIN HYDRIDE

The use of polymer-supported organotin hydride for the cyclisation 1-bromo-2-(prop-2-enyloxy)benzene I to give 2,3-dihydro-3-methylbenzofuran II has been studied. The supports were prepared by suspension copolymerisation of an organotin-functionalised monomer. Two approaches have been investigated either using a stoichiometric or a catalytic amount of organotin support.
