Tc. Lau et al., LEWIS-ACID CATALYZED OXIDATION OF ALKANES BY CHROMATE AND PERMANGANATE, Journal of the Chemical Society. Dalton transactions, (4), 1995, pp. 695-696
The oxidation of alkanes by chromate and permanaganate has been found
to be greatly accelerated by Lewis acids such as BF3 and AlCl3; reacti
on occurs within minutes at room temperature in the presence of just a
few equivalents of the Lewis acids.
