Popis:	Air-stable Pd(II) catalysts with cryptand-22 ligand was easily handled in atm air at room temperature for Suzuki cross-coupling reactions of aryl bromides with arylboronic acids both containing electron-withdrawing and electron-donating groups. Generally, reactions proceeded fast to completion in 2 h to give high product yields. Our Pd(OAc)2/cryptand-22 catalyst is unique, since the reaction solution remained yellow during reaction period and air-stable without formation of Pd black as usually observed for ordinary simple amine ligands.
