Rhenium complexes-catalyzed alkylation of arenes with alkyl halides

Article abstract of DOI:10.1246/bcsj.73.2779

Rhenium complexes have been shown to catalyze the alkylation of arenes with alkyl halides. When arenes were reacted with an alkyl chloride in the presence of a catalytic amount of rhenium complexes, such as bromopentacarbonylrhenium(I) [ReBr(CO)₅], tricarbonylcyclopentadienylrhenium(I) [Re(C₅H₅)(CO)₃] and decacarbonyldirhenium [Re₂(CO)₁₀], alkylation of the arenes proceeded under mild conditions to give a mixture of mono- and dialkyl substituted arenes in moderate-to-good yields.
