Acid dissociation constants in selected dipolar non-hydrogen-bond-donor solvents

This compilation includes more than 9000 pKa values determined in seven dipolar non-hydrogen-bond-donor solvents (dimethyl sulfoxide, acetonitrile, N,N-dimethylformamide, pyridine, acetone, propylene carbonate, tetrahydrofuran) for close to 5000 acids collected from around 800 original works published during the last sixty years. The data have been critically evaluated on the basis of defined quality criteria and depending on situation, kept as they were originally published, marked as doubtful/unreliable (2600 values) or corrected (around 2500 values).

To enable automated processing and mining, the data are presented as an XLSX file, together with structural codes, compound class qualifiers and comments.

All citations should refer to the manuscript:
