Abstract
A process for oxidizing an alkyl substrate may comprise combining an alkyl substrate (e.g., propane, n-butane) and ozone in a liquid phase medium comprising a branched alkane activator (e.g., isobutane) and a protic additive (e.g., water) under conditions sufficient to oxidize the alkyl substrate to products. The alkyl substrate may be selected from linear and cyclic alkanes.
