Av. Bedekar et al., THERMAL VINYLCYCLOPROPANE REARRANGEMENT - AN UNEXPECTED AROMATIZATION, Journal of chemical research. Synopses, (1), 1994, pp. 52-52
Thermolysis of permethric acid derivatives does not give the expected
vinyl cyclopropane rearrangement products, but leads to aromatisation
to afford nw-toluic acid derivatives.
