Experimental acidity data in non-aqueous media

Self-consistent experimental acidity data (pKa data) are presented two organic solvents: MeCN – acetonitrile; DCE – 1,2-dichloroethane. pKa in MeCN and pKip in DCE are directly measured experimental values. --- Additional information on pKa values in acetonitrile: Eur. J. Org. Chem. 2021, 2021 (9), 1407-1419 (https://doi.org/10.1002/ejoc.202001649) --- pKa in DCE is calculated/estimated based on pKip value and serves as an indication of the absolute pKa values in DCE. More information about the calculation procedures and discussion can be found in Chem. Sci., 2017, 8, 6964–6973 (https://dx.doi.org/10.1039/c7sc01424d). For pKip(DCE) values the pKip of picric acid is arbitrarily set to 0.0 and other pKip values are given in reference to the value of picric acid.
