Abstract: Rates and products have been measured in 1: 9 dioxane-water, ionic strength 0.1 M, at 25 OC for the solvolyses of the two diastereomeric bay-region 3, 4-diol 1, 2-epoxides derived from trans-3, 4-dihydroxy-3, 4-dihydrodibenz [c, h] acridine (diol epoxide-1, in which the epoxide and the benzylic hydroxyl groups are cis to each other, and diol epoxide-2, in which these groups are trans). Comparative study of these diol epoxides and their ...
