Abstract
A simple-water soluble diselenide derivative 1 shows radical scavenger prop erties towards alkyl and hydroxyl radicals (k(3) (0 degrees C)=6.8X10(8) M- 1 s(-1)) in Fenton-type chemistry. The reaction rate between produced alkyl radicals 2 and the diselenide overwhelms self-termination and halogen tran sfer reactions. (C) 1999 Elsevier Science Ltd. All rights reserved.
