Donor Strength Determination of Buchwald-Type Phosphines
The electronic properties of eight Buchwald-type phosphines were determined and ranked by <sup>13</sup>C NMR spectroscopy, highlighting the sensitivity of the Huynh electronic parameter (HEP). Furthermore, the <sup>13</sup>C<sub>carbene</sub> NMR signals of 19 known and new P-donor complexes in CDCl<sub>3</sub> (HEP values) are found to be highly correlated to those in C<sub>6</sub>D<sub>6</sub>. This enables the donor strength determination of P-donors even where the complexes are unstable or undergo rapid isomerization due to transphobia in CDCl<sub>3</sub>.
