Reaction Conditions:

with C₄₀H₅₆N₂RuSi₄;hydrogen in toluene at 25; under 760.051 Torr; for 6 h;Schlenk technique;

Steps:

36 [Working Example 36] Hydrogenation of2,3-Dimethyl-2-butene
A magnetic stirrer was placed in a 20 mE Schlenk tubeand the tube was dried by heating under a reduced pressureof 5 Pa, after which the tube interior tube was purged with argon. Ruthenium Complex C (3.9 mg, 0.005 mmol) was added as the catalyst to this Schlenk tube and dissolved in toluene (2 mE). To this solution was added 2,3-dimethyl-2-butene (84 mg, 1.0 mmol). The resulting solution was freeze-pump-thaw degassed, the interior of the Schlenk tube was purged with hydrogen, and the solution was stirred at room temperature for 6 hours. Anisole (108 mg, 1.0 mmol) was added as an internal reference, the ‘H-NMR spectrumwas measured, and the structure and yield of the product were determined. The structure of the resulting compound was confirmed from the ‘H and ‘3C-NMR spectra. These results are shown as Entry 4 in Table 6.‘H-NMR (400 MHz, CDC13) ?=0.84 (d, JHH=6.7 Hz,12H, CH3), 1.40 (septet, JHH=6.7 Hz, 12H, CH).‘3C-NMR (100 MHz, CDC13) ?=19.4, 33.7.
