Abstract

Air-stable defined Ni precatalysts enable a general and efficient coupling of challenging aryl chlorides and in situ generated aliphatic and aromatic thiolates at unprecedented moderate catalyst loadings and reaction temperatures. The reaction tolerates various functional groups and heterocyclic motifs. Depending on reaction conditions, aryl thiols can selectively undergo C-S or C-C couplings.

Note

A fine optimized version of this reaction converts also tertiary thiols and works without any organometallic base. DOI: 10.33774/chemrxiv-2021-tgvjk
