β¦ Synopsis
Perfluoroheptyl)copper reacts with aromatic compounds to give the corresponding perfluoroheptyl arenes. Thus benzene and g-xylene yield (perfluoroheptyl)benzene and l-perfluoroheptyl-2,5dimethylbenzene respectively. Toluene and nitrobenzene afford mixtures of o-and p-substituted compounds. Chlorobenzene yields products derived from halogen displacement as well as the expected o/p mixture.

Ferrocenylamines are excellent catalysts for the enantioselective substitution of unsymmetrical allyl chlorides with dialkylzinc compounds in the presence of a copper(I) salt. For example, in the reaction shown in Equation (1), the product is formed with 87β% ee and a S 2':S 2 ratio of 97:3.
Cuprous carboxylates (acetate, benzoate, pivalate) react with primary, secondary, tertiary, allylic and vinylic halides and tosylates to give the corresponding carboxylate esters. The reaction is executed in refluxing pyridine, under an inert atmosphere and under rigorously anhydrous conditions.
