There are reports on the reduction of ethylene glycol acetals and ketals by aluminum hydrides to the corresponding monoethers. Considering that these compounds find wide application as solvents, plasticizers, and perfume ingredients, it was of interest to study the possibility of a selective hydrogenation of different 1,3-dioxacycloalkanes by industrial grade mixtures of diethylaluminum hydride and triethylaluminum. According to the data obtained for the reactions with cyclic acetals, triethylaluminum is 1. 5-2 times more active than diethylaluminum hydride. The activities of the five-membered ring acetals and ketals in the reduction and alkylation processes are similar; 2-phenyl-1, 3-dioxolane has the highest reactivity. Thus, 2-mono- and 2,2-disubstituted 1,3-dioxacyclanes form monoethers of the correepsponding diols by the action of diethylaluminum hydride and triethylauminum. In the case of triethylaluminum, ethylation of the carbon atom adjacent to the two oxygen atoms takes place.
