The in situ prepared three component system [RhCl(COD)]~2~/imidazolidinium salts (2, 4) and KOBu^t^ catalyses the addition of phenylboronic acid to sterically hindered aldehydes affording the corresponding arylated secondary alcohols in good yields. Four novel 1,3‐dialkylimidazolidinium (2‐4) salts as NHC precursors were synthesized from N,N′‐dialkylethylenediamine.
