Abstract

Lücken nach Wunsch: α-Ethinylphosphole, die in situ aus den entsprechenden silylierten Vorstufen erzeugt wurden, lieferten eine Serie von α-(Arylethinyl)phospholen mit funktionellen Substituenten sowie ein α,α′-verknüpftes Terphosphol (siehe Schema), das wegen der effizienten π-Konjugation über drei Phospholringe eine schmale HOMO-LUMO-Lücke aufweist.
