  InCl3 catalyzed carbene insertion into O–H bonds: efficient synthesis of ethers

  摘要：

  An efficient InCl3 mediated insertion of the carbene fragment (:CHCO2Et), generated in situ from ethyl diazoacetate into O-H bond of a series of saturated and unsaturated alcohols under mild conditions has been developed to afford the corresponding ethers as exclusive products in good to high yields (70-95%) and in shorter reaction times. In the case of unsaturated alcohols, the reaction proceeded with unprecedented selectivity resulting in ethers as the only products and in high yields. (C) 2011 Elsevier Ltd. All rights reserved.
