✦ Synopsis

New 1,

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 KOBu t catalyse the addition of phenylboronic acid to sterically hindered aldehydes affording the corresponding arylated secondary alcohols in good yields.
