The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

Chemists have developed a straightforward method to convert common chemicals like carboxylic acids, alcohols, and alkanes directly into valuable alkenes. Chemists from the National University of ...

Chemical groups containing oxygen, nitrogen, silicon, and other heteroatoms often react during alkene coupling reactions, generating undesirable product mixtures. But a new, iron-catalyzed radical ...

A major advance in alkene oligomerization catalysis was Brookhart’s 1995 report of highly active group 10 metal diimine systems. In contrast to nickel and palladium catalysts, the corresponding ...
