The rates and products of kinetic control in hydrolyses of the unsubstituted and 2-, 6-, and anti-7-methylsubstituted 2-bicyclo [4. l. 0] heptyl3, 5-dinitrobenzoates in 80% aqueous acetone have been determined. These are compared with similar data for the 1-methyl- substituted 3, 5-dinitrobenzoates reported by Wiberg and Chen. Also, they are compared with the results of our previously reported perchloric acid catalyzed alcohol acetolysis ...
