A convenient procedure was developed for the synthesis of 1,2,4,5-tetraoxanes based
on the reaction of gem-bishydroperoxycycloalkanes with ketals and acetals catalyzed by boron trifluoride
etherate, which makes it possible to prepare the target products in yields from 13
to 93%.
tetraoxanes - heterocycles - peroxides - acetals - boron
