HOW DOES AN ALKOXY GROUP AT THE BENZYLIC CARBON AFFECT THE TRANSITION-STATE OF THE HYDROGEN-ATOM ABSTRACTION REACTION - CORRELATION-ANALYSIS OF RELATIVE RATES FOR 14 P-Y-SUBSTITUTED ALPHA,ALPHA-ETHYLENEDIOXYTOLUENES
Xk. Jiang et al., HOW DOES AN ALKOXY GROUP AT THE BENZYLIC CARBON AFFECT THE TRANSITION-STATE OF THE HYDROGEN-ATOM ABSTRACTION REACTION - CORRELATION-ANALYSIS OF RELATIVE RATES FOR 14 P-Y-SUBSTITUTED ALPHA,ALPHA-ETHYLENEDIOXYTOLUENES, Perkin transactions. 2, (7), 1996, pp. 1391-1395
Correlation analysis of the relative rates for the H-atom abstraction
reaction of 14 2-(4-Y-phenyl)dioxolanes (p-Y-substituted alpha,alpha-e
thylenedioxytoluenes, 1-Y) by N-bromosuccinimide (NBS) shows that the
spin-delocalization effect is also operating at the transition state o
f the H-atom abstraction reaction and that the ethylenedioxy group at
the benzylic carbon makes the spin-delocalization more observable than
do two methyl groups.
