Abstract
A BBr3-mediated S-directed ortho C-H borylation of thiobenzamides was developed. A variety of ortho-borylated thiobenzamides were obtained in moderate to good yields with a wide functional group tolerance under simple and metal-free conditions. This transformation provided a convenient and practical route to important functionalized thiobenzamides.

Abstract
Site-selective functionalization of saturated N-heterocycles such as pyrrolidines is a central topic in organic synthesis and drug discovery. We herein report the sulfur-assisted rhodium(III)-catalyzed sp3 C-H amidation of pyrrolidines with dioxazolones as amidating agents. The amenability of the thioamide directing group is elucidated by a series of control experiments.

Abstract
An efficient Cp*Rh(III)-catalyzed regioselective C(sp2)-H mono- and dialkynylation of thioamides was described. This reaction was performed under mild conditions in high yields (up to 98%) with a broad substrate scope. Significantly, the versatility of this method was further demonstrated by controlled mono- and dialkynylation. Application of this protocol in the late stage functionalization of two drug molecules (Adapalene and Amoxapine) was also demonstrated.

Abstract
A thioether directed acyloxylation of arenes has been realized via Cp*Rh(III)-catalyzed C-H activation and subsequent coupling with carboxylic acids. This new method showed high functional group compatibility and broad substrate scope. Primary mechanistic studies have been conducted and a tentative reaction mechanism was proposed. It represents the first example of a thioether-directed Cp*Rh(III)-catalyzed C(sp2)-H acyloxylation reaction.
