Free Radical Halogenation, Selectivity, and Thermodynamics: The Polanyi Principle and Hammond's Postulate
Alfred A. Scala
Department of Chemistry and Biochemistry, Worcester Polytechnic Institute, Worcester, MA 01609
Cover
November 2004
Vol. 81 No. 11
p. 1661
Abstract
Free radical halogenation reactions are examined in the contexts of the Polanyi principle and Hammond's postulate and used as a vehicle for examination of the concept of selectivity in chemical reactions. The origin of selectivity is related to the thermodynamics of the competing reactions and their chemical dynamics.
