Abstract

The concept of green chemistry is fast gaining traction nowadays and in line with the United Nations Sustainable Development Goals. In this manuscript, a simple yet efficient procedure in the synthesis of symmetrical 1,3-diynes using various alkynes catalyzed by copper under base-free and solvent-less condition is presented. With the improved protocol, the formation of homocoupled 1,3-diynes from different alkynes were afforded in good yields. The improved synthetic protocol is in compliance with the principles of green chemistry, which include recyclable catalytic system, avoid the use of base and mild homocoupling reaction condition. The improved protocol can be applied for the synthesis of many desirable compounds that is of interest to the academia and industries.
