Thermochemistry of grignard reagents. Enthalpies of formation of alkylmagnesium bromides and of alkyl bromides

Add time:07/16/2019    Source:sciencedirect.com

The enthalpies of reaction of 17 alkyl halides with magnesium metal in diethyl ether were measured by use of a steady-state heat flow calorimeter. Enthalpies of formation of the alkyl bromides were determined via the enthalpies of reaction of the alkylmagnesium bromides with hydrogen bromide. The carbon-magnesium bond dissociation energies in alkylmagnesium bromides increases in the order: tertbutyl, allyl, benzyl, sec-butyl⋍isopropyl, ethyl, isobutyl, n-butyl, methyl, and phenyl.
