Synthesis of alkynylbenzo-15-crown-5 ethers

Abstract

Reactions of 4′-iodobenzo-15-crown-5 ether with ethynylarenes or 4′-ethynylbenzo-15-crown-5 ether with haloarenes in the presence of catalytic amounts of Pd^II complex salts, CuI, and Et₃N gave 4′-(arylethynyl)benzo-15-crown-5 ethers in 55-80% yields.
