Cyclopropyl radicals normally undergo complete thermodynamic equilibration of configuration before they react, e.g., with bromine in the Hunsdiecker reaction'. Incomplete equilibration is normally due to steric or cage effectsa, and to surface effects when cyclopropyl halides are reduced with metals

In previous work we have reported that Grignard reagents are readily prepared by magnesium bromide capture of the anion produced from the sodium naphthalene reduction of organic halides. 1 The resultant Grignard can be reacted by conventional reagents including organometallic halides to give other
The use of lithium and a catalytic amount of an arene is a well-established methodology for the preparation of organolithium reagents that manifest greater reactivity than the classical lithium-arene solutions. In order to rationalize this conduct, the participation of a highly reduced species, the
The kinetics of the reaction of the sulfate radical, SO4-. with the oxalate anion, CzOz-, was studied in aqueous solution and second-order rate constants, corrected for the effects of ionic strength, derived Measurements were carried out over the temperature range 24-60Β°C resulting in the expression
