Versuchsvorschrift

To a 100 ml stainless steel autoclave, 6.0 mg (0.01 mmol) of complex 1 and 430 mg (2 mmol) of methyl p-bromobenzoate were added, and the autoclave was purged with nitrogen. Then, 0.5 ml (0.5 mmol) of 1 N MeONa and 1.5 ml of methanol were added thereto. Subsequently, hydrogen was introduced to a pressure of 5.0 MPa, followed by stirring at 80° C. for 16 hours. After cooling to room temperature, the reaction product was analyzed by GC. Merely dibromination of 31% of the substrate occurred which resulted in conversion to methyl benzoate (debrominated product), and p-bromobenzyl alcohol was not detected.
