N-Heterocyclic carbenes (NHCs) were functionalized with a triisopropylsilyl (TIPS)-protected alkyne group and self-assembled on Au films to enable post-deposition functionalization by C-C coupling reactions. The TIPS group efficiently protected the alkyne and prevented its deprotonation during surface-anchoring of NHC. Sonogashira C-C coupling reactions were performed on the Au film in high yield following removal of the TIPS group, demonstrating that post-deposition coupling reactions can be employed to widen the chemical scope of surface-anchored NHCs.

An efficient method for the chemoselective and desulfurative Chan–Lam cross-coupling based on benzimidazoline-2-thiones was developed. By modulating the amount of the catalyst Cu(OAc)2·H2O, alkali, temperature, and solvent, the desulfurizational C–N bond formation product (N-arylbenzimidazoles) could be selectively furnished smoothly. The features of this protocol are an inexpensive and readily available catalyst, ligand-free conditions, wide substrate scope, easy performance, and moderate to excellent yields. It shows potential synthetic value for the preparation of a diversity of arylbenzoheterocyclic compounds, which are potentially active in pharmaceuticals and agrochemicals.

The current study presents the design, synthesis, and evaluation of novel cytochrome P450 17A1 (CYP17A1) ligands. CYP17A1 is a key enzyme in the steroidogenic pathway that produces androgens among other steroids, and it is implicated in prostate cancer. T
