Abstract

The homocoupling of alkyl halides utilizing a highly activated form of zerovalent copper has been studied. Allyl and benzyl halides produce high yields of their respective homocoupled dimers 1, 5-hexadiene and 1, 2-diphenylethane. An 83% yield of tetradecane was produced from n-heptyl iodide. The yield drops substantially for the corresponding bromo and chloro compounds. The yield is also strongly solvent and temperature dependent. Secondary ...
