Efficient and highly selective oxidation of primary and secondary alcohols by butyltriphenylphosphonium chlorochromate under non-aqueous conditions
195-198Butyltriphenylphosphonium chlorochromate 1
(BTPPCC) is used as a new and selective reagent for the oxidation of benzylic
and allylic alcohols to the corresponding carbonyl compounds in refluxing
acetonitrile
Oxidation of alcohols with 1-butyl-4-aza-1-azoniabicyclo[2.2.2]octane chlorochromate (BAAOCC) under non-aqueous conditions
577-5801-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
An efficient and novel method for the synthesis of aromatic sulfones under solventfree conditions
