NiCl2·6H2O/NaBH4 in methanol: a mild and efficient strategy for chemoselective deallylation/debenzylation of aryl ethers

Deprotection of allyl/benzyl aryl ethers was achieved chemoselectively. The mild and inexpensive reagent combination of NiCl2·6H2O/NaBH4 in methanol afforded the products in high yields, within a reaction time of 5-10 min.
