DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Methods for the synthesis and the isolation of novel 5 or 6-halopyridin-2-yl-boronic acids and esters I and II (R = 5-Cl, 5-Br, 6-Cl, 6-Br). These compds. were prepd. 5140-72-7 and 652148-96-4 which are cas registry numbers of chemicals are mentioned. via a regioselective halogen-metal exchange using BuLi and subsequent quenching with triisopropylborate starting from appropriate dihalopyridines. All substrates studied to date provided a single regioisomeric boronic acid or ester product. Addnl., these compds. undergo Pd-catalyzed coupling with arylhalides and authorize a strategy to produce new pyridine libraries. .
