Reaction Studies on the Conversion of Aryl Methyl Halides to Aryl Carbonyl Compounds Using Ph4PBr/EDTA/CaF2 as a Catalytic Oxidation System
We have developed an efficient protocol for the selective oxidation of arylmethyl halides to aromatic carbonyl compounds. This transformation employs tetraphenylphosphonium bromide (Ph4PBr) as both an oxidant and phase-transfer catalyst (PTC), in combination with EDTA and CaF2 as cocatalysts. Under mild reaction condit...
