N. Redouane et al., TRIARYLPHOSPHINES - MOLECULAR-GEOMETRY, ANODIC BEHAVIOR AND ESR STUDYOF THE RADICAL CATIONS, Phosphorus, sulfur and silicon and the related elements, 77(1-4), 1993, pp. 653-656
A large series of triarylphosphines has been prepared and their geomet
ry was studied by force field calculations. A very good agreement was
found between the calculated and experimental (X Ray) geometries. The
oxidation potentials were determined by electrochemical techniques and
the corresponding cations were studied by ESR. Both the oxidation pot
entials and the ESR features were shown to depend strongly on the mole
cular geometry.
