of nido‐carboranes (7,8‐nido‐C2B9H12−) has been developed under electrochemical reaction conditions. In this reaction system, anodic oxidation serves as a green alternative for traditional chemical oxidants in the oxidation of nido‐carboranes. No transition‐metal catalyst is required and different heteroatoms bearing a lone pair are reactive in this transformation. Coupling nido‐carboranes with thioethers

exchanging the 2-methyl group on the indole ring in the ester and amide series with a hydrogen also generated inactive compounds. Inhibition kinetics revealed that indomethacin amides behave as slow, tight-binding inhibitors of COX-2 and that selectivity is a function of the time-dependent step. Conversion of indomethacin into ester and amidederivatives provides a facile strategy for generating highly selective
