trans-Stilbene → Dibenzyl

Participants

Reaction Steps

According to the general procedure, a solution of trans-stilbene (50 mg, 0.28 mmol) and rac-32 (8.8 mg, 0.0056 mmol, 2.0 mol %) in CH2Cl2 (3 mL) was pressurized with H2 to 62 bar and stirred for 48 h. Filtration of the reaction mixture and evaporation of the solvent gave 39 (50 mg, 97%). mp 48-50° C. (lit.1 47-49° C.) 1H NMR (300 MHz, CDCl3): δ 7.39-7.25 (m, 10H), 3.01 (s, 4H); 13C NMR (75.5 MHz, CDCl3): δ 141.9, 128.6, 128.5, 126.0, 38.1.
