car·bon·i·um

(kar-bon'ē-ŭm),
An organic cation in which the positive charge is on a carbon atom;,for example, (CH3)+. It is now recommended that carbocation be used as the class name and carbenium for specific compound names.

carbocation

An often reactive anion with a positively charged carbon that has six electrons in its outer valence shell—i.e., it is missing two electrons that would ensure maximum stability.

Chloro-containing compounds are known to form carbocations, especially for chloride bonded to allylic or benzylic groups (ref.
The benzyl chloride is the most reactive, because the carbocation intermediate formed is stabilized by resonance into the aromatic group.
may indicate a greater usefulness for the carbocations generated from
His most recent efforts have been directed towards solid-state NMR and x-ray crystallographic studies of isolable carbocations, the thermal and photochemistry of iminium salts related to the visual pigments, and the use of photochemical methods for the fabrication of charge-mosaic piezodialysis membranes.
After setting out principles and practice, they cover the photogeneration of carbon-centered radicals, heteroatom-centered radicals, biradicals and radical pairs, radical ions, carbocations and carbanions, and cargenes and nitrenes.
This result indicates that the reactivity of the carbocationic species generated during the polymerization process, which includes the initiating carbocations and chain propagating carbocations, were reactive enough to polymerize the vinylether groups of the VESFA, but not so reactive that they add to double bonds of the fatty acid portion of VESFA.
But the silicon cation proved more difficult to make than the carbocation.
