The DPPH and alkyl radical scavenging activities (RSA) were computed following equation in which H and H0 were the relative peak height of radical signals with and without sample, respectively.
Alkyl radical quenching yields alkoxyamines whose stability to thermolysis and disproportionation depends on the alkyl substituent (Scheme 4; [R.
Ferrocene is known to readily form charge transfer complexes (CTCs) with alkyl halides, as evidenced by the appearance of a feature indicative of a charge transfer complex at ~310 nm; subsequently, upon irradiation, the complex dissociates into the ferrocenium ion, chloride ion, and alkyl radical (Fig.
