Aryl chlorides and fluorides are smoothly hydrodehalogenated by irradiation either in neat i-PrOH or in a polar solution in the presence of hypophosphorous acid or triethylsilane. The procedure gives the halogen-free products in good to excellent yields under mild eco-friendly conditions and avoids the recourse to toxic metal catalysts.

Abstract
Aryl chlorides and fluorides are smoothly hydrodehalogenated by irradiation either in neat i-PrOH or in a polar solution in the presence of hypophosphorous acid or triethylsilane. The procedure gives the halogen-free products in good to excellent yields under mild eco-friendly conditions and avoids the recourse to toxic metal catalysts.File in questo prodotto:
