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.
