A novel, highly efficient, and mild protocol has been developed for the synthesis of O-aryloxime ethers in good to excellent yields at ambient reaction conditions. This is the first report in which =N-O-Ar linkage was achieved with ecofriendly, recyclable, heterogeneous copper fluorapatite (CuFAP) catalyst via C-O cross coupling of aryloxime with arylboronic acid in the presence of Cs2CO3 as base and methanol as solvent.
