摘要：
Iridium pincer complexes (POCOP)Ir(CO) (POCOP = kappa(3)-C6H3-1,3-[OP(Bu-t)(2)](2)) and substituted POCOP derivatives catalyze deoxygenation of glycerol to n-propanol and 1,3-propanediol in good yield under moderate conditions (acidic aqueous dioxane, 200 degrees C, 80 bar H-2). Catalyst solubility in the polar reaction mixture is improved by incorporation of a polar moiety in the para position of the POCOP phenyl ring, with the best results obtained with a dimethylamino substituent.
