No full text577-5801-Butyl-4-aza-1-azoniabicyclo[2.2.2]octane
chlorochromate (BAAOC) in the presence of AlCl3 affords an efficient
and mild system for oxidation of a variety of alcohols, giving the
corresponding aldehydes and ketones in refluxing acetonitrile. The experimental
procedure is simple and the products are isolated straightforward in good to
excellent yields.</i
