The slight differences in the donor capabilities of PPhnPy3-n (n = 0-3) could be measured directly in the equilibrium of phosphine replacement reaction on (η5-C5H5)Fe(CO)2-phosphi ne complexes, taking advantage of the radical pathway to establish equilibrium rapidly. The simultaneous determination of equilibrium constants is done in a single experiment. The donor capability increases in the order PPh3 2Py 2 3 with quantified (η5 - C5 H5) Fe (CO)2+-affinity scales at 1, 4.90, 11.0, and 20.3, respectively.
