Quantifying solvent effects through QSPR: A new look over different model equat...
Moreira, Luís; Elvas Leitao, Ruben; Abraham, Michael; Martins, FilomenaThe heterolysis reactions of 3 tertiary alkyl halides (2-chloro-2-methylpropane, 2-bromo-2-methylpropane and 3-bromo-3-ethylpentane) in a set of 21 protic and aprotic solvents, representative of various classes of solvents, were used to study solvent effects upon reactivity, at 298.15 K. Quantitative Structure-Property Relationships established through the use of multiple linear regressions, namely a model equa...
