Synthesis of 1,4-diarylsubstituted 1,3-diynes through ligand-free copper-catalyzed oxidative decarboxylative homocoupling of aryl propiolic acids

An efficient method of ligand-free Cu-catalyzed oxidative decarboxylative homocoupling of aryl propiolic acids was developed. When CuI was employed as the catalyst and I2 as the oxidant, the decarboxylative homocoupling reaction for Csp/s

Synthesis method of asymmetric conjugated diyne

The invention provides a synthesis method of asymmetric conjugated diyne. The synthesis method comprises the following steps of A, mixing a catalyst with phenanthroline and a strong base, then adding cis-alkenyl bromide, terminal alkyne and a solvent in an argon atmosphere, and agitating, refluxing and making an obtained mixture react for 20h to 24h under a condition of 140 to 150 DEG C; B, extracting, drying and concentrating a product, and then separating and purifying the product through column chromatography, so that the asymmetric conjugated diyne is obtained. Compared with the prior art, the synthesis method provided by the invention is low in cost, easy in the obtaining of raw materials, relatively convenient to operate, high in efficiency, wide in serviceable range and suitable for the reaction of multiple substrates; further, the catalyst can be recycled.

Cu-catalyzed Fe-driven Csp-Csp and C sp-Csp2 cross-coupling: An access to 1,3-diynes and 1,3-enynes

An efficient Csp-Csp cross-coupling of alkynyl bromide and pinacol ester of alkynyl boronic acid catalyzed by CuFe 2O4 nanoparticles has been accomplished in dimethyl carbonate to produce unsymmetric 1,3-diynes. This protocol is also extended for the Csp-Csp2 coupling of alkynyl bromide and alkenyl boronic acid to provide conjugated 1,3-enynes. The aliphatic, aromatic, and heteroaromatic alkynes couple with various substituted alkynyl/alkenyl boronates/boronic acids by this procedure to furnish a library of 1,3-diynes and enynes in high yields. The catalyst was easily separated by an external magnet and recycled 10 times.
