First Stereoselective Total Synthesis of Ciryneol C
The acetylene derivative Ciryneol C was isolated from the roots of C. japonicum. The asymmetric total synthesis of Ciryneol C was achieved in seven steps, with Horner–Wittig olefination, regioselective epoxide opening, and Cadiot–Chodkiewicz coupling ...

Nitrogen fixation sensitivity related to water use efficiency at reproductive development in soybean
Soybean [Glycine max (L.) Merr.] nitrogen fixation is sensitive differentially to drought among different genotypes at different growth and development stages, which directly affects soybean yield. Acetylene reduction activity (ARA) response to a gradual

Effect of Coal Grain Size on Sorption Capacity with Respect to Propylene and Acetylene
Propylene and acetylene are released to mine air with the increase in the temperature of self-heating coal. Concentrations of these gases in mine air are applied as indicators of the progress of the self-heating process.

Mechanism of Semi-Hydrogenation of Trace Acetylene in Ethylene by [MB12Hx]2-
[Purposes] The main problem of semi-hydrogenation of trace acetylene in ethylene is excessive hydrogenation. High concentration of ethylene is the main cause of excessive hydrogenation, so it is important to design a catalyst with acetylene enrichment ...
