Abstract:RUNNING HEAD: The Grignard reaction with alkoxysilanes ABSTRACT The kinetics of the reaction of n-butyl-and isopropylmagnesium chloride with alkyltriethoxysilanes (RSi(OEt) 3 ) in diethyl ether were determined. The rate constants correlate well with the steric parameters E s (Si). The resulting steric factors δ fit the range of available susceptibility values for the reactions of organosilicon compounds. The thermodynamic activation parameters for six reactions of ethoxysilanes with alkylmagnesium chlorides in… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
