- The kinetics and mechanism of the reaction of tricoordinate phosphorus compounds with sulfenate esters
-
The kinetics and mechanism of the reaction of tricoordinate phosphorus compounds, ArnP(OCH2CF3)3-n with arylsulfenate esters, ArSOCH2CF3, are reported. Product analysis, kinetic order, activation parameters, Hammett data and solvent effects are the criteria used to elucidate the two step mechanism involving arylthiophosphoranes as intermediates.

- THE THERMOLYTIC DECOMPOSITION OF ACYCLIC PHOSPHORANES
-
The thermolytic decomposition of acyclic phosphoranes, ArnP(OCH2CF3)5-n in aprotic media has been shown by kinetic studies to proceed via rate-limiting ionization of the phosphoranes.Activation parameters, deuterium isotope effects, solvent effects and ρ-values (for n = 3 and n = 1) support this concept which is consistent with the observed rate-sequence of n = 3> n = 2 > n = 1 > n = 0.Key words: Phosphoranes, thermolysis, kinetics, mechanism.
