Regioselective vicinal diamination of carbon–carbon double bonds with two different amines is a synthetic challenge under transition metal-free conditions, especially for the synthesis of trifluoromethylated amines. However, the synthesis of ethylene di
Besides the addition of an electrophilic species to a carbon–carbon double bond that was examined in the preceding section, an alternative way to create a carbocation is to remove one electron from the double bond. This can be achieved either by chemical means (strong oxidants, formation of ch...

To determine which carbon-carbon bond has the minimum bond length, we need to analyze the types of carbon-carbon bonds and their respective bond lengths. 1. Understanding Bond Types: - Carbon can form three types of bonds w
The synthesis of complexes between UCl4 and carbodiphosphoranes (CDP), which formally possess double dative bonds Cl4U⇇CDP, is reported in this paper. Single-crystal X-ray diffraction shows that the uranium−carbon distances are in the range of bond lengths for uranium−carbon double bonds...
