Reactive electrophilic species

WebNitrosamines are not so reactive as nitrosating agents as are their counterparts the alkyl nitrites, probably because of the strength of the N-N bond. However there are a number of cases which have been reported which show that nitrosation can occur using nitrosamines. The hydrolysis (or denitrosation) or nitrosamines has been well studied. WebAug 12, 2024 · A positively charged species such as a carbocation is electron-poor, and thus anything which donates electron density to the center of electron poverty will help to stabilize it. Alkyl groups, because of the electrons in their carbon-carbon and carbon-hydrogen bonds, are weak electron-donating groups, and will stabilize nearby carbocations.
