YieldReaction ConditionsOperation in experiment
67% A solution of N,N′-tetramethylsuccinic acid diamide (20 mmol) in dichloromethane (20 ml) is admixed with triethyloxonium tetrafluoroborate (8.36 g, 44 mmol) and stirred under argon for 3 hours on the water bath at 40 C. The mixture is then concentrated in vacuo, and the residue is taken up in 50 ml of absolute ethanol. An autoclave cooled in the ice bath is charged with catalyst (1 mol %) and 20 ml of 2M sodiumethylate solution in ethanol, flushed with argon and filled with the reaction mixture in ethanol. 40 bar of hydrogen are then injected in, and the mixture is stirred at 25 C. and a constant pressure until hydrogen absorption is no longer evident (1-12 h). After filtration over Celite, the filtrate is worked up as in Examples 10-28. (0189) The catalysts used and yields of N,N′-tetramethyl-1,4-butanediamine can be found in Table 7.
