Creator:: Totherow, William D.
Abstract:: A study of the relative rates of benzylic hydrogen abstractions from a series of meta and para substituted neopentylbenzenes by the bromine radical and trichloromethyl radical at 70°C has been carried out. Application of the Hammett equation yields p values of -0.75 for the bromine atom and -0.94 for the...

Abstract:: A three part study involving aspects of radical properties of various aromatic species was accomplished. Experiments to ascertain the importance of geometric and electronic effects on the intramolecular transfer of a pi-complexed radical to a terminal double bond was performed. Several 4-aryl-1-butenes were reacted in competition with 1-undecene with a...

Abstract:: A study of the effects of structural modification at the alpha position of ethyl 2-bromocarboxylates on their rates of addition to two alkene pairs was undertaken. In the competition between 3-propoxypropene and 1-octene at 70°, a 37% increase in selectivity was observed in going from carboxylates generating primary radicals to...

Creator:: Mahiou, Belaid
Abstract:: The relative rates of hydrogen atom abstraction from a series of 13 homoaryl and heteroarylmethanes by the nucleophilic undecyl radical, thermally generated from lauroyl peroxide, were determined at 70 °C. A reactivity range of 15 was obtained. Substantial differences in reactivity among isomers were found. The relative reactivities of the...

Creator:: Newkirk, David Dudley
Abstract:: The relative rates of hydrogen abstraction from 1-phenylalkanes and a,w-diphenylalkanes using N-bromosuccinimide and bromotrichloromethane were determined at 70°C. In both cases the reactions were photoinitiated. Only benzylic bromination was observed. The 1-phenylalkanes reacted with both reagents to give rates largely independent of substrate. Similarly, the rate of the reaction between...
