    • All experiments were carried out under an inert gas atmosphere (argon) with exclusion of air. For the standard reaction procedure NaOH or sodium is dissolved in 4 mL of iso-propanol at 90°C in a double walled thermostated reaction vessel. The solution containing the catalyst and the ligand in 1 mL iso-propanol is prepared in a Schlenk tube and added to the reaction vessel at 90°C via septa and a small teflon tube after refluxing became stationary. Starting with addition of the catalyst the progress of the reaction is followed by several analytical methods. The amount of generated hydrogen is measured by gas burette. In addition a hydrogen sensor of the Fa. Hach Ultra Analytics GmbH is used for analysis of hydrogen and a GC for analyzing gases is applied (gas chromatograph HP 5890, permanent gases: Carboxen 1000, TCD, external calibration; alkanols, aldehydes/ketones: HP Plot Q, 30 m, FID). Aldol condensation products and hydrogenation of the aldol condensation products are analyzed by gas chromatography (HP 1, 50 m, FID, internal standard). The reproducibility of the results is between 12% and 15%
