Synthesis of 3-aryl-1H-indazoles via iridium-catalysed C–H borylation and Suzuki–Miyaura coupling†
Abstract
The regioselective iridium-catalysed C3-borylation of 1H-indazoles has been achieved. Subsequent Suzuki–Miyaura coupling of the boronate esters with aryl chlorides, bromides and iodides affords 3-aryl-1H-indazoles in good yields.
