Tritellurasumanene: ultrasound assisted one-pot synthesis and extended valence adducts with bromine†
Abstract
Tritellurasumanene is synthesized from a triphenylene skeleton via ultrasound assisted one-pot reaction. This compound adopts a flat conjugated system and displays Te⋯Te (3.83 Å) interactions in the solid state. Its optical properties and chemical reactivity are quite different from those of its trithia- and triselena-analogues.
