实验步骤: A two-liter three neck round bottom flask was equipped with a magnetic stirrer, a heating mantle, a thermocouple, a glass stopper and a Dean Stark trap fitted with a condenser. 4,4′-Methylenebis(2,6-diethylbenzeneamine) (310.5 g, 1.00 mol) and methyl ethyl ketone (450 mL, 350 g, 4.85 mol) were added to the flask. This mixture was stirred at 40° C. to dissolve the 4,4′-methylenebis(2,6-diethylbenzeneamine). Hexanes (300 mL) and Amberlyst-15 (15.54 g) were added to the flask. The mixture was heated to reflux, and water was removed as an azeotrope in the Dean Stark trap. Samples were periodically taken and analyzed by gas chromatography (GC). N,N′-di-sec-butylidene-4,4′-methylenebis(2,6-diethylbenzeneamine) was formed in 94.7% yield. GC results are summarized in Table 1; units for the diamine, monoimine, and diimine are GC area percent.

实验步骤: 4,4′-Methylenebis(2,6-diethylbenzeneamine) (3 g), Pt(S)/C (0.3 g), Amberlyst-15 (0.3 g), methyl ethyl ketone (25 g), and tetrahydrofuran (THF; 25 g) were charged into a 100 mL metal autoclave at 22° C. The closed autoclave was purged 3 times with 90 psig (7.22×105 Pa) of H2 at 22° C. The reaction mixture was then heated at 100-120° C. under 125 psig (9.63×105 Pa) of H2 for 5 hrs (until no further H2 uptake was observed). The product mixture was cooled to 22° C. and degassed. A diluted product sample was analyzed by GC (180° C. for 5 minutes at 10° C. per minute rate; final temperature, 270° C.). The GC data (normalization method) showed 100% conversion of 4,4′-methylenebis(2,6-diethylbenzeneamine), and an 86% yield of N,N′-di-sec-butyl-4,4′-methylenebis(2,6-diethylbenzeneamine).
