Abstract

original image

Direkt: Mit [Pd2(dba)3] als Katalysator gelang die direkte Alkinylierung von unterschiedlich substituierten Thiophenen mit terminalen Alkinen als Alkinylierungsreagentien. Das Protokoll kann auch für andere elektronenreiche aromatische Heterocyclen verwendet werden. dba=Dibenzylidenaceton.
