As a result, methyl alcohol molecules were separated from DMP and formed carbocations. After a methoxyl was lost, steric hindrance was reduced, so it would be easily attacked by the nucleophilic reagent.
One of the cancerogenic mechanisms is based on the release of bladder toxic carbocations from xenobiotic conjugates, by hydrolysis, during its elimination with urine.
Methyl radicals (Equation 1) or, alternatively, carbocations (Equation 2) (collectively termed radicals) that potentially form are highly reactive species and would lead eventually to the formation of pyrophoric TMA and TMS inside HVAC&R systems.
Many organic reactions, including industrially significant reactions in biomass processing and petroleum refining, involve chemical intermediates known as carbocations, which feature positively charged carbon atoms.
(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.
The carbocations do not readily form because of the poor electron donating capability of primary carbon atoms.
