Synthetic Access to Pentacene‐Silylene Adducts via Dehydrogenative Silylation of a 5,14‐Dihydropentacene with a Stable Silylene

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...
