An iridium/bipyridine-catalyzed ortho-selective C?H borylation of aryl sulfides was developed. High ortho-selectivity was achieved by a Lewis acid–base interaction between a boryl group of the ligand and a sulfur atom of the substrate. This is the first example of a catalytic and regioselective C?H transformation controlled by a Lewis acid–base interaction between a ligand and a substrate. The C?H borylation reaction could be conducted on a gram scale, and with a bioactive molecule as a substrate, demonstrating its applicability to late-stage regioselective C?H borylation. A bioactive molecule was synthesized from an ortho-borylated product by converting the boryl and methylthio groups of the product.

The metallation reactions of (methylthio)anilines with organolithium reagents and with the butyllithium-potassium tert-butoxide superbasic mixture are here described. The results show that the para isomer when treated with butyllithium gave a mixture of p
