Tamiki Komatsuzaki, Ikuo Akai, Kazuhisa Sakakibara, Minoru Hirota

Graphical Abstract

log (k /kO) = varrhoΩS + a′ A new steric substituent constant, ΩS, was proposed in order to evaluate the kinetic steric effect. varrhoS is isotropic and dependent most significantly on the number of α-carbon atoms. The rates of several reactions were shown to be correlated with ΩS better than with Es.

Ali Hashem Essa

Graphical abstract

The correlation analysis of Mulliken charge (QM) calculated by using density functional theory (B3LYP/STO-3G) calculations of 1-(4-azido-5-hydroxymethyl-tetrahydro-selenophen-2-ylmethyl)-5-substituted-1H-pyrimidine-2,4-dione, were done by using mono substituent parameter (Hammett’s model), and dual substituent parameter (Taft’s, Reynolds’, and Swain’s models). The dual substituent parameter correlations of the QM data gave no significant improvement over single parameter correlations, the best correlation observed with the Taft’s Model as compared with the Swain’s and Reynolds’ Models, respectively. The correlation analysis of Mulliken charge can be used successfully to demonstrate the existence or absence of the interaction between the oxygen of the carbonyl group and selenium atom.

Graphical abstract

Kinetics of reactions of ethyl- and phenylmagnesium chlorides with chlorosilanes, RMeSiCl2, were investigated. Rate constants for alkyl substituted silanes correlate with Es(Si) steric parameters. The inductive constants σ* derived from the carbon chemistry are not applicable to the silicon chemistry.
