Iron mediated catalytic reactions are of great interest in the field of organic synthesis because they are economic and naturally abundant. However, the use of iron catalyst in the field of free radicalcyclization or reduction of alkyl halides remains limited. Here we describe the use of an unprecedented combination of iron and zinc in the reduction and 5‐exo‐trig radicalcyclization of alkyl halides

Perhydrofuro-2,3b furans have been prepared in high yield by radicalcyclisation of unsaturated bromo acetals. Their transformation into tetrahydro derivatives is described along with a radical annelation to 2,3- dihydrofurans by tributyltin iodoacetate.
