Gem-dihalocyclopropanes bearing a phenyl group and an additional group were nitrated by using nitric acid in a sulfuric acid matrix. The products from the nitration of aryl rings are major. The presence of a methyl group on the C(2) position of the cyclopropane ring leads to the isoxazoline from nitration at the C(1)-position instead of that from nitration at the C(2)-position.
