Amines mercury-photosensitized

Mercury photosensitization in the presence of NH3 leads to partial defluorination and functionalization of a variety of perfluoroalkanes to give perfluoroalkyl imines, amines, and nitriles (Scheme 40). Polytetrafluoroethylene can be surface functionalized by this method to give a hydrophilic surface. DFT studies suggest that the [Hg (NH3)2l excited state complex may be involved as a key intermediate.
