16. Ethynyl-cyclohexanol: an efficient acetylene surrogate in Sonogashira coupling

Ethynyl-cyclohexanol: an efficient acetylene surrogate in Sonogashira coupling, Márton Csékei, Zoltán Novák, András Kotschy, Tetrahedron 2008, 64, 975-982. DOI10.1016/j.tet.2007.10.031 |

The Sonogashira coupling of aryl halides in the presence of 1-ethynyl-cyclohexanol as an acetylene source provides an efficient method for the synthesis of diarylacetylenes without the isolation of the appropriate arylacetylenes.
