Abstract
The rate of protonation of singlet 2-fluorenylnitrene was studied in eight protic solvents. The protonation rates vary between 10(11) and 10(9) s(-1) and are well-correlated with Swain's acity parameters. This demonstrates that Swain acity parameters and nitrene protonation rates can be used to evaluate bulk solvent acidity.
摘要
在八种质子溶剂中研究了单线态2-芴基氮烯的质子化速率。质子化速率在10¹¹至10⁹ s⁻¹之间变化，并且与斯温酸度参数具有良好的相关性。这表明斯温酸度参数和氮烯质子化速率可用于评估本体溶剂酸度。
