Alkene cross-metathesis, using ruthenium-based catalysts, in principle offers just that: a method for combining two alkene fragments to give an intermediate that can undergo cyclization to give ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

Chemists from the National University of Singapore (NUS) have developed an iron-catalyzed method that overcomes a significant challenge in the sustainable synthesis of trisubstituted Z-alkenes by ...

For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. Addition polymerisation uses addition reactions to turn alkenes into polymers.

Homometathesis and cross-metathesis coupling of phosphine-borane templates with electron-rich and electron ... In contrast, C5-amino-modified dUTPs with alkane or Z-alkene linkers and their ...
