Reductive deprotection of aryl allyl ethers with Pd(Ph3)4/NaBH4

Treatment of aryl allyl ethers with catalytic amts. of Pd(PPh3)4 and NaBH4 at room temp. afforded the parent phenol in high yield under non-hydrolytic conditions. E.g., treatment of ether I (R = allyl) with NaBH4 in the presence of Pd(PPh3)4 in THF gave 97% I (R = H). [on SciFinder (R)]
