Özet
There novel 1,3-dialkylperhydrobenzimidazolinium (2a-c) and two 1,3-dialkylimidazolinium salts (4a,b) as NHC precursors were synthesized from N,N'-dialkyl-1,2-cyclohexanediamine dihydrochloride and 1,2dialkylpropanediamine dihydrochloride.The in situ prepared three component system [RhCl(COD)] 2 / imidazolinium 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.
