A novel synthesis of per(poly)fluoroalkyl aldehydes in high yield by the reaction ofper(poly)fluoroalkyliodides or bromides with dimethylformamide initiated by aPbBr2(catalyst)/Al bimetal redox system is described.

In the presence of catalytic amounts of stannous salts (20 mol%) and aluminium powder, per(poly)fluoroalkyliodides or bromides react smoothly with DMF under mild conditions to give the corresponding per(poly)fluoroalkyl aldehydes in good to excellent yield. A tin-containing intermediate was obtained. A possible mechanism is proposed.
