The eliminations of nitrous acids from the compounds (1) and (6) are E2 processes, which proceed with a large primary kinetic isotope effect and with antiperiplanar stereochemistry.The rate of elimination of HNO2 fom (1) is intermediate between the rate o
Isotope effects in nucleophilic substitution reactions. IV. The effect of changing a substituent at the α carbon on the structure os SN2 transition states

, p. 2500 - 2520 (2007/10/02)
Kinetic studies, secondary α-deuterium kinetic isotope effects, primary chlorine kinetic isotope effects (1), Hammett ρ values determined by changing the substituent in the nucleophile, and activation parameters have been used to determine the detailed (relative) structures of the transition states for the S2 reactions between para-substituted benzyl chlorides and thiophenoxide ion.A rationale for the U-shaped Hammett ρ plots observed when para-substituted benzyl compounds react with negatively charged nucleophiles is also presented.
