Copper powder-mediated homocoupling reactions of iodoacetylenes to synthesize symmetrical 1,3-butadiynes

A new route to synthesize symmetrical 1,3-butadiynes from iodoacetylenes in the presence of copper powder and pyridine was developed. Moderate to excellent yields were obtained through an efficient and simple process involving the copper powder without any further activation. Copyright Taylor & Francis Group, LLC.

Copper Catalysis for Selective Heterocoupling of Terminal Alkynes

A Cu-catalyzed selective aerobic heterocoupling of terminal alkynes is disclosed, which enables the synthesis of a broad range of unsymmetrical 1,3-diynes in good to excellent yields. The results disprove the long-held belief that homocouplings are exclusively favored in the Glaser-Hay reaction.

Synthesis of 5,10,15,20-meso-unsubstituted and 5,10,15,20-meso-substituted- 21,23-ditellura/diselena core-modified porphyrinogens: Oxidation and detection of mercury(ii)

Tellurium and selenium incorporated 5,10,15,20-meso-unsubstituted-21,23- ditellura/diselena core-modified porphyrinogens (N2Te2 and N2Se2), 5,10,15,20-meso-unsubstituted-21-tellura/selena core-modified porphyrinogens (N3Te and N3Se) and fully substituted meso-carbons porphyrinogens (N2Te2, N 2Se2 and higher analogs) are synthesized by 3 + 1 condensation of tellurophene/selenophene dipyrranes and their corresponding diols in the presence of BF3-etharate or BF3-methanol. The meso-unsubstituted and substituted porphyrinogens were oxidized with chloranil/0.1% aqueous FeCl3 in CHCl3 at room temperature to obtain the corresponding porphines and porphyrins which are further reduced to corresponding chlorin and bacteriochlorin, whereas the fully meso-substituted porphyrinogens were found to be good ligands for Hg2+. The structures of the products were characterized by IR, 1H, 13C, 125Te, 77Se NMR, CHN analysis, mass spectrometry and single-crystal XRD.
