Synthesis of Aryl Thiocyanates, Aryl Dithiocarbamates, Aryl Sulfones, and Aryl Thiobenzoates via Au-Catalyzed C–S Cross-Couplings

We have developed an efficient gold-catalyzed C-S cross-coupling of various silver-based thionucleophiles with aryl iodides. Our method offers a one-stop-shop solution for synthesizing diverse sulfur-containing aromatics, including aryl thiocyanic acids, aryl diethyldithiocarbamates, aryl sulfones, and aryl thiobenzoates. Our protocol gives moderate to excellent yields and compatibility with various functional groups. In comparison to other transition-metal-catalyzed C-S cross-couplings, our method has advantages in broad applicability and high tolerance toward air and moisture.
