The crude tri-n-pentyl (3-(trifluoromethyl)benzyl)ammonium chloride product was recrystallized from a methyl ethyl ketone-hexane mixture and dried. The product was recovered in a yield of 27.6 grams (71.5 percent of theoretical) and melted at 151.5°-152.5° C. The structure of the compound was confirmed by NMR (Compound 3).

The autoclave was subsequently closed and CO2 was injected at room temperature. H2 was then injected and the reactor was heated while stirring (700 rpm). After the desired reaction time, the autoclave was cooled and the hydrogenation mixture (H) was depressurized. Unless indicated otherwise, a two-phase hydrogenation mixture (H) was obtained, with the upper phase (U1) being enriched in the still free tertiary amine (A1) and the homogeneous catalyst and the lower phase (L1) being enriched in the polar solvent and the formic acid-amine adduct (A2) formed. The total content of formic acid in the formic acid-amine adduct (A2) was determined by potentiometric titration with 0.1 N KOH in MeOH using a “Mettler Toledo DL50” titrator. The turnover frequency (=TOF; for the definition of the TOF see: J. F. Hartwig, Organotransition Metal Chemistry, 1st edition, 2010, University Science Books, Sausalito/Calif. p. 545) and the reaction rate were calculated therefrom. The composition of the two phases was determined by gas chromatography. The ruthenium content was determined by atomic adsorption spectroscopy (=AAS). The parameters and results of the individual experiments are shown in Tables 1.1 to 1.5. Examples A-1 to A-17 show that high to very high reaction rates of up to 0.98 mol kg-1 h-1 are achieved in the process of the invention even with variation of the tertiary amine (A1), the polar solvent, the catalyst in respect of the ligands and the metal component, the amount of the catalyst and the amount of water added. All systems examined formed two phases, with the upper phase (U1) in each case being enriched in the still free tertiary amine (A1) and the homogeneous catalyst and the lower phase (L1) in each case being enriched in the polar solvent and the formic acid-amine adduct (A2) formed.

The solution obtained was subsequently warmed to room temperature (about 20° C.) and degassed by evacuation (2 hPa abs) and admission of pure nitrogen, carried out a total of three times. A two-phase solution was obtained. This was then transferred under an N2 atmosphere in a glove box into a 270 ml autoclave (material: HC) and the autoclave was closed. The autoclave was subsequently pressurized with nitrogen to 1.0 MPa and heated to 160° C. while stirring vigorously. After the temperature had been reached, a total pressure of 2.5 MPa abs was set by injection of further N2. The reaction mixture was then stirred at 160° C. for 24 hours. The autoclave was subsequently cooled to room temperature, depressurized to atmospheric pressure and the contents were transferred to a glass vessel. The output separated into two phases. 36.8 g of upper phase and 59.3 g of lower phase were obtained. Both phases were analyzed by gas chromatography to determine their di-n-pentylformamide content. The upper phase comprised 0.15% by weight, and the lower phase comprised 0.45% by weight.

70% With oxygen; ferric nitrate In dimethyl sulfoxide for 48h; Irradiation; 2 Preparation of 2-propylquinoxaline Take the quartz reaction tube, add a magnetic stir bar to it, and then add 0.3 mmol of o-phenylenediamine and 0.6 mmol of tripentylamine,10mmol% of photosensitizer iron salt (Fe(NO3)3), and finally add 1mL of dimethyl sulfoxide (DMSO).Then add a three-way gas head with a balloon above the quartz reaction tube, first freeze the reaction stock solution completely with liquid nitrogen, then use an oil pump to vacuum the quartz reaction tube, and then fill the balloon with oxygen; stir with a magnetic stirrer Under oxygen conditions, the reaction was carried out under blue LED light for 48 hours. The final product was detected by TLC and finally separated by column chromatography to obtain the final product 2-propylquinoxaline with a yield of 70%.
