Article abstract of DOI:10.1002/hlca.19960790306

The synthesis of functionalized 1,1,2,2-tetraethynylethanes(= 3,4-diethynylhexa-1,5-diynes) as synthons for tetraethynylethenes (3,4-diethynylhex-3-ene-1,5-diynes) and as building blocks for three-dimensional acetylenic molecular scaffolding targeting the
