An efficient and complementary copper-catalyzed alkylation of (benzo)furans/(benzo)thiophenes with cyclic ethers was reported. A broad range of C2 heteroaryl-substituted cyclic ethers were obtained in moderate to good yields. The results of control experiments indicated that this transformation might proceed via a radical process.

铜与呋喃和噻吩衍生物与环醚的铜介导烷基化

报道了用环醚有效和互补的铜催化的（苯并呋喃）/（苯并）噻吩的烷基化。以中等至良好的产率获得了广泛的C 2杂芳基取代的环状醚。对照实验的结果表明，这种转变可能是通过根本过程进行的。
