Abstract

A molecular tweezer bearing two pentafluorophenyl groups 2b and its o-methylated aryl homologue 2c were newly synthesized by the slight modification of the known procedure. The low yield in the introduction of pentafluorophenyl group to the precursor dibromide 6 was improved by application of the modified Suzuki-Miyaura coupling reaction using C₆F₅B(OH)₂ with Pd₂(dba)₃/P(t-Bu)₃/CsF/Ag₂O catalytic system, which was recently developed by us.
