An enabling continuous flow setup for handling of unstable organolithium intermediates and synthesis of heteroaryl sulfinates on a multigram scale is described. The developed continuous flow process allows for the synthesis and simple isolation of heteroaryl sulfinates which are otherwise challenging to access in classical batch mode. The lithium sulfinate salts prepared by this method were shown to be efficient reaction partners in palladium catalyzed C(sp2)-C(sp2) cross-coupling to access medicinally relevant bis-heteroaryl motifs.
