Notes:
The hydrogen abstraction reactions of tert-butoxyl with germane, phosphine, and trimethylsilane were studied by pyrolyzing di-t-butyl peroxide in the temperature range of 403 to 458 K. From the reported rate constant for the tert-butoxy radical decomposition in the literature, the absolute rate constants were determined from the study of competitive reaction between t-butoxy radical decomposition \documentclass{article}\pagestyle{empty}\begin{document}$$ (t - {\rm BuO }\;{\hbox to 45pt{\rightarrowfill}} {\hskip-42pt ^{{\rm decompose}}}{\hskip1em} {\rm CH}_{\rm 3} {\rm COCH}_{\rm 3} + {\rm CH}_{\rm 3}) $$\end{document} and hydrogen abstraction reaction.
