Photopolymerization of diacetylenes usually requires stringent reaction conditions like high energy irradiation of 254-nm light or even γ-rays, which are generally harmful to the human body and thus mild conditions with lower energy irradiation are requir

The invention provides a method for synthesizing a 1,3-butadiyne compound by catalyzing molecular oxygen to oxidize a water phase by a water-soluble transition metal complex. A water-soluble metal complex formed by complexing a transition metal and a water-soluble ligand is a catalyst; in an oxygen or air environment, an alkynyl silanes compound or a terminated alkynes compound reacts in an alkaline water phase to generate the 1,3-butadiyne compound; and the reaction pressure is 0.01 to 0.5 MPa, the reaction temperature is 40 to 100 DEG C, and the reaction time is 4 to 24 hours. According to the method provided by the invention, the synthesis step is simple, the reaction conditions are mild, the operation is simple, convenient and feasible, and the product yield is 99 percent; furthermore,the method is applicable to a wide range of substrates, and a new concept is provided for synthesis of the conjugated 1,3-butadiyne compound; the reaction is performed in the water phase without adding other organic solvents; and the catalyst is high in catalysis activity and high in reaction efficiency, can be used for multiple times, produces a small number of products, and has a relatively good industrial application prospect.

Krauss, Jürgen,Kopp, Ursula,Bracher, Franz
, p. 637 - 641 (2016/02/18)
The naturally occurring oxygenated bibenzyls lunularin and m-O-methyllunularin were prepared in a modular synthesis in four steps from two appropriate iodophenols and trimethylsilylacetylene utilizing microwaveassisted Sonogashira couplings as the crucial steps. The antimicrobial activity of the resulting natural products was evaluated in an agar diffusion assay.

With the aim to achieve rapid and efficient topochemical polymerizations in the solid state, via solution-based processing of thin films, we report the integration of a diphenyldiacetylene monomer and a poly(styrene-b-acrylic acid) block copolymer templat
Pd-catalyzed decarboxylative coupling of propiolic acids: One-pot synthesis of 1,4-disubstituted 1,3-diynes via Sonogashira-homocoupling sequence

experimental part, p. 2214 - 2219 (2011/06/11)
One-pot synthesis of symmetric 1,4-disubstituted 1,3-diynes from iodoarenes and propiolic acid via Sonogashira reaction followed by Pd-catalyzed decarboxylative homocoupling is developed in high yields. Also, this system allows the one-pot synthesis of unsymmetric 1,4-disubstituted 1,3-diynes by cross-coupling of two different 3-substituted propiolic acids.
