Regioselective reductive openings of mixed phenolic-benzylic cyclic acetals, using BH3-NMe3-AlCl3, under mild conditions to yield a benzylic ether and free the phenol group have been attributed to association of boron with the more basic oxygen (benzylic) followed by reaction with aluminium chloride.309... 

Fluorinated methyl aryl ethers. The facile rearrangement of oxygenated benzyl derivatives effected by XeFa to give fluorinated methyl ethers, i.e., benzyl alcohols to fluoromethyl aryl ethers and benzaldehydes to difluoromethyl aryl ethers, may involve the formation of fluoroxy intermediates and thence oxaspirobenzenium ions. 

Oxidation. This compound has been used to promote the oxidation of alcohols to ketones by oxygen. Benzylic CHj is also oxidized.

The carbanions formed by scission of a C-Si bond with TASF can also be oxygenated. Benzylic trimethylsilyl groups can be converted to hydroxyl groups in 20-95% yield by reaction with TASF(Me) in the presence of oxygen and Trimethyl Phosphite (eq 17). No other source of fluoride ion was found that could replace TASF.
