Efficient Synthesis of Tribenzohexadehydro[12]annulene and Its Derivatives in the Ionic Liquid

A simple and efficient synthesis of tribenzohexadehydro[12]annulene and related derivatives in the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate is described. A Sonogashira coupling reaction is the key step. In this system, the amount of CuI normally used can be reduced so that homocoup...

Zusammenfassung:A simple and efficient synthesis of tribenzohexadehydro[12]annulene and related derivatives in the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate is described. A Sonogashira coupling reaction is the key step. In this system, the amount of CuI normally used can be reduced so that homocoupling is minimized.
