Homocoupling of terminal alkynes catalyzed by copper complexes of 1,10-phenanthroline under base- and solvent-free conditions

Abstract EN

Environmentally friendly chemistry growing in popularity as it conforms with the United Nations Sustainable Development Goals.

This research shows a a simple yet efficient procedure for the synthesis of symmetrical 1,3-diynes using various alkynes catalyzed by copper under base-free and solvent-less conditions.

With the improved protocol, the formation of homocoupled 1,3-diynes from different alkynes were produced in adequate amounts.

The improved synthetic protocol is in compliance with the principles of "green" chemistry, which includes recyclable catalytic systems and which avoids the use of base and mild homocoupling reaction conditions.

The improved protocol can be applied to the synthesis of different compounds that are necessary in industry.
