Özet
New 1,3-dialkylperhydrobenzimidazolinium and 1,3-dialkylimidazolinium salts (2,4) as NHC precursors have been synthesized and characterized. These salts in combination with [RhCl(COD)]2 provided active catalysts for the addition of phenylboronic acid to aldehydes under mild conditions. The in situ prepared three-component system [RhCl(COD)]2/imidazolinium salts (2,4) and KOBut catalyse the addition of phenylboronic acid to sterically hindered aldehydes affording the corresponding arylated secondary alcohols in good yields. © 2005 Wiley Periodicals, Inc.
