Route of Synthesis (ROS)
| Conditions | Yield |
| With [C6H3-2,6-(OP(tBu)2)2]IrH2; trifluorormethanesulfonic acid; water; hydrogen In 1,4-dioxane at 125℃; under 5171.62 Torr; Temperature; Pressure; Solvent; Autoclave; Experimental Procedure 11 Hydrogenation of 1,2 Propanediol. Hydrogenation of 1,2 Propanediol. Using (POCOP)IrH2 and trifluoromethanesulfonic acid, 1,2-propanediol (1,2 PD) was reduced to n-propanol in up to 95% yield in aqueous dioxane at 125° C. under 100 psi H2. The mild conditions of the reaction and the high selectivity observed are extraordinary. Even more remarkable is the stability of this catalyst to the aqueous environment. In fact, the presence of water is actually required to achieve high deoxygenation selectivity and hydrogenation efficiency, which also increased as the acid concentration in the reaction system was decreased. | 95% |
