実験手順

In a pressure reactor made of stainless steel and having an internal volume of 50 ml, 0.05 mmol of [Ru(CO)3Cl2]2 as a ruthenium compound, 0.05 mmol of Co2(CO)8 as a cobalt compound, and 0.25 mmol of butylmethylpyrrolidinium chloride as a halide salt were introduced and mixed at room temperature, and thus a catalyst system was obtained. 5.0 mmol of norbornene and 5.0 mL of methyl formate were added to this catalyst system, subsequently the reactor was purged with nitrogen gas at 0.5 MPa, and the system was maintained for 15 hours at 120° C. Thereafter, the reactor was cooled to room temperature, and the pressure was released. A portion of the remaining organic phase was withdrawn, and the components of the reaction mixture were analyzed by using gas chromatography. According to the analysis results, the amount of methyl norbornane monocarboxylate produced by the reaction was 7.07 mmol (yield in terms of norbornene 70.7%).
