Synthesis of 2-aryl derivatives of pentaborane(9)

Article abstract of DOI:10.1021/ic00142a002

A series of 2-aryl derivatives of B₅H₉ have been prepared via aluminum chloride catalyzed electrophilic substitution by 2-ClB₅H₈ on various alkylbenzenes. Analyses of ¹H NMR spectra suggest that the site of attack of the B₅H₈ moiety is controlled by steric interactions.
