A 5-cyano substituent decelerates the solvolysisrate of exo-2-norbornyl brosylate (1-H) by a factor of 1790. A much smaller deceleration (24–90 fold) is observed for the secondary endo and for both exo and endo tertiary 2-norbornyl derivatives. These results support the occurrence of σ-participation in the solvolysis of 1-H.
