Organic Chemistry Frontiers, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 1, 2024

Pyrroles functionalised with a thianthrenium or diphenylsulfonium group undergo Stille couplings aryl alkynyl stannanes in good yields, avoiding the issues of instability that can hamper use analogous pyrrolyl halides.
