Phenacyl anilinium salts

Phenacylammonium Salts Phenacyl anilinium salts have light absorption 300-350 nm that make them preferable for photoinduced cationic polymerization. Upon irradiation, these salts undergo either a heterolytic cleavage or a homolytic cleavage followed by an electron transfer to yield a cation intermediate that in turn can initiate polymerization of appropriate monomers [16]. Scheme 11.14 shows the mechanism in detail. As can clearly be seen, the photolysis of phenacylammonium salts are irreversible and different than their sulfonium analogs [43].
