Cobalt-catalyzed homocoupling of terminal alkynes: Synthesis of 1,3-diynes

Homocoupling of terminal alkynes proceeds using Co2(CO)8 pretreated with phenanthroline to give good yields of 1,3-diynes under mild conditions.

Trithiocarbonate Anion as a Sulfur Source for the Synthesis of 2,5-Disubstituted Thiophenes and 2-Substituted Benzo[ b]thiophenes

The trithiocarbonate anion (CS32-) was generated in situ from CS2 and KOH in dimethyl sulfoxide by a simple method and used as a novel synthetic equivalent of the S2- synthon for the synthesis of 2,5-disubstituted thiophenes from 1,3-butadiynes. Additionally, this system was employed for the metal-free synthesis of 2-substituted benzo[b]thiophenes from 2-haloalkynyl (hetero)arenes. These compounds were obtained from a cheap and readily available sulfur source in moderate to good yields, with good functional group tolerance.

Copper-Mediated Deacylative Coupling of Ynones via C-C Bond Activation under Mild Conditions

The intermolecular deacylative coupling of unstrained ynones via C-C bond activation was accomplished by a CuCl-bpy system under mild reaction conditions. This protocol features facile cleavage of the C-C bond at room temperature, broad substrate scope, and efficient construction of important symmetric and unsymmetrical 1,3-diyne adducts through homo or cross coupling of ynones, respectively. The preliminary mechanistic investigations indicated that an acyl copper(III) complex is likely involved in this process.

Polymer-Supported Cu–Nanoparticle as an Efficient and Recyclable Catalyst for Oxidative Homocoupling of Terminal Alkynes

Abstract: Copper nanoparticle on polyaniline support was synthesised by using in situ polymerisation and composite formation technique. This metal polymer nanocomposites material is found to be efficient for homocoupling of terminal alkynes which afford s
