Synthesis of per(poly)fluoroalkyl aldehydes from per(poly)fluoroalkyl chlorides
摘要:
Per(poly)fluoroalkyl aldehydes can be conveniently synthesized from per(poly)fluoralkyl chlorides by their reaction with DMF promoted by a PbBr2(catalyst)/Al bimetal redox system at room temperature.

Fluoroalkyliodides react with alkenes in the presence of catalytic amounts of iron to give the corresponding adducts in good yields, the influence of solvent on the reaction is discussed and a SET initiated radical chain mechanism is proposed.
The reaction of polyfluoroalkyl iodides with alkenes or 4-pentenoic acid promoted by sodium bisulfite or sodiumsulfite in DMF aqueous solution was realized. The reaction of alkenes gave corresponding adducts, while γ-lactones were obtained in the case of 4-pentenoic acid in good yields.

Perfluoroalkyliodides reacted with alkenes in acetonitrile solution containing catalytic amounts of an organophosphine under mild conditions to give the corresponding adducts in moderate to high yields. Addition of hydroquinone to the reaction mixture suppressed the reaction. Diallyl ether reacted to afford tetrahydrofuran derivatives. These findings indicated that the reaction involved a free radical
