Room-temperature Transformation of Alkyl to Vinyl Carbocations in Organic Solutions: A New Path to Stable Vinyl Cation Salts | Chapter 5 | Chemical and Materials Sciences: Research Findings Vol. 5

 

It was found that alkyl carbocations, such as tert-butyl and methylcyclopentyl cations, decompose to unsaturated vinyl-type carbocations when their salts are dissolved in common organochlorine solvents. These transformations yield thermally stable vinyl cation salts, which were characterised by IR spectroscopy and, in some cases, X-ray crystallography. This method provides a convenient approach to isolating crystals of vinyl carbocation salts and studying them in solution, with implications for understanding carbocation stability and reactivity beyond superacidic media.
