AI Technical Summary
⚠Technical Problem
Conventional synthesis schemes for alkynes often require harsh reaction conditions, costly raw materials, and result in poor yields with many by-products that cannot be reused or recycled.
⚗Method used
A multistep process involving the reaction of a metal with an alkyne reactant to form a metal acetylide or propynide, followed by contacting it with a haloalkane to produce a metal salt and C4-C20 alkynes, utilizing suitable solvents and conditions to enhance yield and selectivity.
🎯Benefits of technology
The process achieves high yields of C4-C20 alkynes with minimal by-products, allowing for efficient production and recycling of reactants, thereby reducing costs and environmental impact.

Abstract
Alkyne compounds are produced by contacting a metal and an alkyne reactant comprising acetylene and / or propyne in a first reaction medium to form a first reaction mixture comprising a metal acetylide and / or a metal propynide, and then contacting the metal acetylide and / or the metal propynide with a haloalkane in a second reaction medium to form a second reaction mixture comprising a metal salt and a 1-alkyne and / or a 2-alkyne. Representative alkynes that can be produced using this process include 1-hexyne, 2-hexyne, 2-heptyne, and the like.
