An efficient fluoride-mediated O-arylation of sterically hindered halophenols with silylaryl triflates under mild reaction conditions
摘要:
The reaction between 2,6-dihalophenols and 2-(trimethylsilyl)aryl triflates in the presence of CsF using acetonitrile as solvent at room temperature led to the formation of functionalized diaryl ethers in very good yields. (C) 2011 Elsevier Ltd. All rights reserved.
