of the 3-hydroxymethyl derivative, radiolytic generation of semiquinoneradicals and HPLC analysis indicated that efficient elimination of the leaving group occurred following one-electron reduction of the parent compound. The active species in leaving group elimination was predominantly the hydroquinone rather than the semiquinoneradical. The resulting iminium derivative acted as an alkylating agent
