Abstract

Utility of a thermally stable divalent silicon species (silylene) toward the dehydroaromatization of a dihydropentacene is demonstrated. The reaction of a cyclic (alkyl)(amino)silylene with 6,13-dipropyl-5,14-dihydropentacene afforded the corresponding pentacene-silylene adducts. The reaction likely proceeds through a combination of 1,4-dehydrogenation and (1+4) cycloaddition of the silylene towards the dihydropentacene.
