Iodine-catalyzed reactions of bis(1-hydroperoxycycloalkyl) peroxides with ketals give, via replacement of two alkoxy groups, the cyclic peroxides, 1,2,4,5,7,8-hexaoxonanes, in up to 82% yields. The cyclization is very sensitive to the solvent nature. Among MeCN, Et2O, THF, CHCl3, CH2Cl2, hexane, and MeOH, the best results were achieved with the first three solvents.
碘催化双(1-氢过氧环烷基)过氧化物与酮的反应,通过取代两个烷氧基基团,产生了环状过氧化物--1,2,4,5,7,8-六氧羰烷,收率高达 82%。环化反应对溶剂性质非常敏感。在 MeCN、Et2O、THF、CHCl3、CH2Cl2、己烷和 MeOH 溶剂中,前三种溶剂的效果最好。
