We report a new and efficient iron oxide catalyzed cross-coupling reaction between organometallic species such as alkyl/arylmagnesium halides or organolithium species and α-hydrogen bearing cyclic unbranched and branched aliphatic ethers via activation of C(sp3)–H. In the presence of 1 mol% of iron oxide, five and six membered unbranched cyclic ethers such as tetrahydrofuran and tetrahydropyran gave

reaction between organometallic species such as alkyl/arylmagnesium halides or organolithium species and alpha-hydrogen bearing cyclic aliphatic ethers via activation of C(sp(3))-H. This is the first example of iron oxide mediateddirect C-C bond formation without expensive or toxic ligands.
