“…We measured the molecular weight of the diiodo complex in dichloromethane to be 606 g/mol. This value quite clearly indicates that there is no significant amount of association of the molecular units even in a non-coordinating solvent such as dichloromethane (21). Fortunately, the permethylated species also forms single crystals suitable for X-ray crystallographic analysis.…”

3492 (1985) Using multivariational statistical methods, the calculation and interpretation of empirical parameters of the polarity of solvents has been reexamined. The size of the sample used (57 aprotic solvents and 24 protic solvents) assures that it is representative. For each solvent, the data tabulated include some physical constants (dielectric constants, dipole moments, refractive indices, molar refractions, boiling points, Hildebrand's 6 parameters) or theoretical values (energy levels of frontier orbitals). The methods used are factorial analysis and multiple regression. The results obtained show that, for the aprotic solvents, the parameter ET is a measure of the polarity, of the polarizability, and of the cohesion of the solvent to the extent of 43, 39, and 18% respectively. For the parameter a*, these proportions are respectively 53, 18, and 29%. For the protic solvents, the parameter ET is explained by the same variables except for 5 solvents more acidic than water; this anomaly is explained by the basicity of the oxygen of the betaine used to define ET.[Journal translation] IntroductionDans les approches quantitatives de I'effet des solvants sur les processus chimiques, une propriCtC mesurant cet effet est considCrCe comme une fonction linCaire, soit d'un ou plusieurs paramktres empiriques, soit d'une ou plusieurs grandeurs physicochimiques du solvant, soit de combinaisons des deux types de variable.De nombreuses Cchelles empiriques ont Ct C proposies pour rendre compte: (i) de la polarisabilitC et de la polarit6 des Ces Cchelles ont en commun d'Ctre dCfinies par la variation de propriCtCs spectroscopiques d'une ou plusieurs molCculessondes (ou de propriCtCs thermodynamiques de reactions modkles) quand on passe d'un solvant a un autre.
