The reactivity of the carbon−carbon double bond differs from the chemical surroundings of the double bonds. The oxidation of the double bonds in the aliphatic chains just requires the use of hydrogen peroxide [18]. However, stronger oxidative reagents such as m-chloroperbenzoic acid (m-CPBA)...

although these methanediides are very effective at stabilising mid and high oxidation state uranium ions, they are conversely ill-disposed towards preparing uranium(III)-derivatives, and so the synthesis of a polarised-covalent uranium(III)-carbon double bond presents an inherent and unmet challenge....

nucleophilic difunctionalization of alkenes with simple amines without the use of transition metals would be a cornerstone to improve structural diversity of diamine synthesis. This vicinal amination of the carbon–carbon double bond under metal free conditions has been presented with bifunctional nucleophile...

Various cinnamate derivatives were tested as inducers for reduction of C–C double bonds in Acetobacterium woodii. The double bond and a phenyl ring were essential for induction, since crotonate and hydrocaffeate were ineffective as inducers whereas cinnamate derivatives were effective. Induction was ...
