Chang, Suae-Chen published the artcileAttempt to observe neighboring group participation in hydrogen abstraction from β-(substituted phenyl)-ethyl bromides, Safety of 1-(2-Bromoethyl)-3-(trifluoromethyl)benzene, the publication is Journal of Organic Chemistry (1975), 40(25), 3800-1, database is CAplus.
A series of β-(substituted phenyl)-ethyl bromides are reacted with bromotrichloromethane at 70°. Benzylic hydrogen abstraction comprises the only reaction. The exptl. ρ value for this process is -0.83 ± 0.02. A ρ value is calculated to have the range of -0.84 to -0.90. The negligible difference between these two ρ values is indicative of no anchimeric assistance in this reaction by the neighboring bromine atom under the conditions utilized.
