Kinetics of the reactions of isocyanates, isothiocyanates, carbodiimides, carbon disulfide, and carbon dioxide with carbanions or enamines (reference nucleophiles) have been measured photometrically in acetonitrile or DMSO solution at 20 °C. The resulting second-order rate constants and the previously published reactivity parameters N and sN of the reference nucleophiles were substituted into the correlation log k2(20 °C) = sN(N + E) to determine the electrophilicity parameters of the… Expand

Nucleophilic Magnesium Silanide and Silaamidinate Derivatives.
DFT calculations demonstrate that the previously reported reaction of [(BDI)Mg-n-Bu] with the silaborane Me2PhSi-Bpin provides the magnesium silanide derivative, through the intermediacy of a short-lived silyl-pinacolato-organoborate species, to be a consequence of the enhanced electrophilicity of the N-aryl-substituted carbodiimide reagent.
