Carbocations often quickly rearrange before proceeding with a reaction and some rearrangements are slower than others.
8) Although carbocations are generally very reactive species, polymerization processes have been developed that enable very controlled polymerization.
MINDO/3 is particularly good for describing carbocations, including non-classical carbocations, and polynitro organic compounds.
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.
The resulting carbocations may undergo (Beta)-scission followed by an inter/ intramolecular hydrogen transfer, leading to different products (benzene, ethylbenzene, cumene, etc.
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.
Chloro-containing compounds are known to form carbocations, especially for chloride bonded to allylic or benzylic groups (ref.

formation of carbocations from the deamination of N-substituted
Normally existing for less than one-millionth of a second as "reaction intermediates" generated during the breakup of hydrocarbon molecules, the positively charged carbocations could, under the superacid's influence, be observed and analyzed in a way previously impossible.
Chapters discuss specific categories such as organometallics, carboranes, carbocations, or transformations that proceed through transient hypercarbon species, with information on fundamental chemistry, including reactivity, selectivity, stereochemistry, and mechanistic factors.
