“…Mori and coworkers have pioneered the concept of an oxidative acetylenic homocoupling directly from a trialkylsilyl-protected acetylene, thus forming a diyne without the need for isolation of the terminal alkyne precursor [88]. This concept has also been applied to polyynes [89].…”

“…We observed a similar advantage using this solvent in the oligomerization of platinum-bridged tetraethynylethenes under Hay conditions (Section 4.3). [50] A solution of the acetylene is heated together with one equivalent of CuCl in DMF under air or dioxygen to give the coupled product in high yield (Scheme 7). [49] In the presence of oxygen-sensitive products or reactants, large excesses of the Hay catalyst (CuCl, TMEDA) have been used to shorten the reaction time.…”

“…[49] In the presence of oxygen-sensitive products or reactants, large excesses of the Hay catalyst (CuCl, TMEDA) have been used to shorten the reaction time. [50] Oxidative coupling reactions are usually the method of choice for the construction of macrocyclic oligoacetylenes containing buta-1,3-diynediyl fragments. [50] A solution of the acetylene is heated together with one equivalent of CuCl in DMF under air or dioxygen to give the coupled product in high yield (Scheme 7).…”

“…[43,49] Eine interessante Vorschrift von Mori, Hiyama und Mitarbeitern erlaubt die direkte Kupplung Trimethylsilyl-geschützter Acetylene ohne vorherige Entfernung der Schutzgruppen. [50] [50] der Silylschutzgruppen, z. B. Fluoridionen, sind hierbei überflüssig.…”
