A unique synergistic combination of lipase and ionic liquid [hmim]Br is reported for metal-free H2O2 activation, which is the first example of biocatalytic promiscuity of CAL-B for chemoselective oxidation of aryl alcohols/acetates. The catalytic system exhibits excellent functional group compatibility under neutral conditions besides reusability up to ten cycles thereby making the process economically and environmentally viable.
