Abstract A direct oxidative transformation of phenol derivatives to the corresponding tetrahydrofuranyl ethers via C–Hbondactivation, in the presence of copper catalyst and desired products were achieved in good yields using TBHP as an oxidant.

Iron catalyzed oxidative coupling of salicylaldehydes with cydic ethers proceeded through the direct a-C H functionalization of ethers, forming the corresponding acetals in moderate to excellent yields. This is the first example of iron catalyzed selective C-O bond formation in the presence of a sensitive aldehyde moiety.
