Abstract

Abstract: Second-order rate constants for halogen atom transfer (kRx) in benzene at 50" C were determined for reactions of wtyl radical with? err-butyl, isopropyl, and cyclohexyl iodides and bromides and with ethyl iodide, n-butyl bromide,? err-butyl chloride, and carbon tetrachloride using two methods. In method A, an alkyl iodide and tributylstannane were allowed to compete for octyl radical in radical-chain reactions; in method B, an alkyl halide ...
