Abstract

An ultrasound-assisted synthesis of symmetrical 1,3-diyne compounds with electron-withdrawing or -donating substituents is described and illustrated by the palladium-catalyzed homocoupling reaction of n-butyl alkynyltellurides. This procedure offers easy access to 1,3-diynes in very short reaction times, and the products are achieved in good to excellent yields.

Transition-metal-free variant of Glaser- and Cadiot-Chodkiewicz-type Coupling: Benign access to diverse 1,3-diynes and related molecules
2020, Tetrahedron Letters
Efficient and transition-metal-free transformations towards the synthesis of 1,3-diynes have been described from their corresponding terminal acetylenes or 1,1-dibromo-1-alkenes. The efficiency of molecular iodine as catalyst in aqueous medium, driven the transformation to afford 1,3-diynes in moderate to good yields. The developed reaction conditions revealed appreciable functional group tolerance in aqueous medium. Further, the scope of the transition-metal-free approach for the synthesis of 1,3-enynes has been investigated using terminal alkynes as easy available precursors.

Thiophenes prepared from diynes were firstly reported by Reisch and Schulte in 1960.48 Later, Kagan and co-workers had used this method to prepare the α-thiophene oligomers in 1982.49 By this novel method, Kagan had prepared a series of thiophene oligomers in moderate to high yields.9b
Conjugated diynes have attracted more and more attention not only for their unique rod like structures and wide existence in nature product, but also the abundant properties and derivations of them. Although oxidative dimerization of alkynes or Cadiot–Chodkiewicz reactions were the main pathway and have achieved great success in the synthesis of diynes, oxidative cross coupling, FBW rearrangement as well as diyne metathesis emerged rapidly recently. Moreover, diynes could be precursors of basic heterocycles, which represented an emerging research area. This Letter will cover the recent progresses in the synthesis and further derivations of diynes.

Citation Excerpt :
Reaction with alkyl halide generated a high yield (Table 3, entry 9, 89% yield), while those using TMS–Cl gave a yield of 31% and chlorodiphenylphosphine as the electrophile, 89% (Table 1, entries 10 and 11, respectively). Functionalization was also possible through the Suzuki–Miyaura cross-coupling reaction using potassium aryltrifluoroborate salts catalyzed by palladium complexes.21 Initially, we focused our attention on the optimization of the reaction conditions.
