of 5-(bromomethyl)cycloheptene with tributyltin hydride gave bicyclo[3.2.1]octane; similar reduction of 5-(bromomethyl)cyclo-octene gave bicyclo[4.2.1]nonane together with some bicyclo[3.3.1]nonane. The cyclohept-4-enylmethyl radical intermediate exists as a rapidly equilibrating mixture of conformers, including the axial boat form from which cyclisation occurs. The rates of the two main cyclisation

Cyclohept-4-enylmethyl radicals undergo transannular cyclisation to give bicyclo[3.2.1]octane; likewise, bicyclo[4.2.1]nonane and bicyclo[3.3.1]nonane are obtained from cyclo-oct-4-enylmethyl radicals.
