Abstract

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

Discussions

• Really pleased that the latest (and final) paper from Jodie Hann's PhD work @uniofbath.bsky.social has now been published. Read about how pyrrolyl sulfonium salts can be used for the cross-coupling o [bsky, 4 points, 0 comments]
