摘要

In the presence of a base catalyst (20 mol %) such as DBU, DABCO or Na2S & sdot; 3H(2)O/N-methylpyrrolidone, phenylacetylenes were found to efficiently undergo sulfurative amination with elemental sulfur and anilines under neat conditions, leading to N-aryl thioamides with complete atom efficiency.
