  Silver-Catalyzed Synthesis of 1-Chloroalkynes Directly from Terminal Alkynes

  摘要：

  AbstractAn efficient method to prepare 1‐chloroalkynes was investigated. The method involved the use of readily available terminal alkynes and a catalytic amount of a silver salt with N‐chlorosuccinimide as the chlorinating agent under mild conditions. Compared with the existing process, this method has a broad substrate scope: 19 examples were explored, and the products were obtained in excellent yields and were easily isolated by vacuum distillation. Moreover, recycling of the catalyst was achieved by simple filtration and desiccation, which made the method more economic and environmentally benign.

  Gold-Catalyzed Oxidative Cross-Coupling of Terminal Alkynes: Selective Synthesis of Unsymmetrical 1,3-Diynes

  摘要：

  Gold-catalyzed oxidative cross-coupling of alkynes to unsymmetrical diynes has been achieved for the first time. A N,N-ligand (1,10-Phen) and PhI(OAc)2 were identified as crucial factors to promote this transformation, giving the desired cross-coupled conjugated diynes in excellent heteroselectivity (>10:1), in good to excellent yields, and with large substrate tolerability.

  Direct halogenation, including chlorination, bromination and iodination of terminal alkynes, are of great importance in organic synthesis. Here an efficient and recyclable nano-Ag/g-C3N4 catalyst system was developed and proved to be remarkably active with 39 examples varied from chlorination, bromination to iodination, of which 14 runs have yielded more than 95% of the product. Recycling of the catalyst

  A facile catalytic enantioselective 1,2‐addition of diynes to trifluoromethyl ketones was developed. By a combination of Me2Zn, Ti(OPr‐i)4, BaF2 and quinine, the reaction of a series of terminal diynes with trifluoromethyl ketones proceeded to afford trifluoromethylated chrial tertiary alcohols with the diyne moiety in good to high yields with moderate to high enantioselectivities.
