1-Alkynes of even carbon numbers from 6 to 18 were polymerized by using W, Mo, and Fe catalysts to give poly(1-alkynes), a type of comb-like polymer with a rigid conjugated polyene main-chain. n=4 to ...

Metathesis reactions for making compounds that contain carbon-carbon multiple bonds are one of the most important sets of processes in the chemical industry. The alkene or alkyne products are widely ...

In a showcase of metal hydride catalysis, two research groups have developed reactions to transform simple unsaturated building blocks—alkenes and alkynes—into valuable chiral amine products. What ...

(Nanowerk News) The role of surface modification of nanoparticle catalysts in alkyne hydrogenation reactions was systematically investigated by the Center for Nanoscale Materials' NanoBio Interfaces ...
