Homofugality:: A new reactivity index describing the leaving group ability in homolytic substitution reactions

We propose and test a new reactivity index tentatively called homofugality, to quantitatively rank the leaving group ability of radical fragments present in homolytic substitution reactions. The model is validated for a series of S(H)2 processes involving organometallic systems. (c) 2006 Elsevier B.V. All rights reserved.
