Abstract
PURPOSE: To obtain the titled compound selectively in high yield with easy separation and recovery of an oxidizing agent after a reaction, by oxidizing 1,3-dioxolan and 1,3-dioxane using ruthenium tetroxide as an oxidizing agent.
CONSTITUTION: A compound shown by the formula I (R1 is H, alkyl, or aryl; R2 and R3 are H, or alkyl; n is 0 or 1) is oxidized by ruthenium tetroxide, to give compounds shown by the formula II (R2 is alkyl), formula III (R3 is alkyl), formula IV (R2 is H) and formula V (R3 is H). In the oxidation of ruthenium tetroxide, the reaction is carried out using CCl4, or CCl4-water system as a solvent, and in the latter case, inexpensive NaOCl is used as a cooxidizing agent. For example, in the reaction in CCl4, a solution of RuO4 in CCl4 is previously prepared, and this solution is added dropwise to the compound shown by the formula I/CCl4 solution. The concentration of RuO4 is properly 10W100mol/l.
