Table 1. Results of the basicity measurements of phosphanes in acetonitrile.[a]
[a] Bases investigated in this work are given in bold, the data for the other bases are taken from the literature. [b] The pKa values are
taken from the literature.[5] [c] The pKa values given to two decimal digits are more reliable than the pKa values given to one decimal
digit (see text for more information).
