実験手順: (The procedure described for the trans isomer in JCS Perkin I, 1999, 25, 3023 was used.) A mixture of cis-cyclohexane-1,4-dicarboxylic acid (TCI) (24.1 g, 140 mmol), butyl formate (700 ml, 623 g, 6.10 mol, 43.5 equiv.), and Dowex 50W×2 resin (50-100 mesh, 140 g) in octane (700 ml) was stirred under nitrogen in a 110° C. oil bath for 24 hours. The mixture was cooled to ambient temperature. The supernatant solution was decanted away from the resin. The resin was washed with ethyl acetate: hexane (1:1, five 150 ml portions), and the washings were added to the supernatant. The solution was evaporated under reduced pressure, the resulting residue diluted with toluene (25 ml), evaporated under reduced pressure, and dried to give crude cis-4-(butoxycarbonyl)cyclohexanecarboxylic acid (36.5 g) as a yellow oil: 1H NMR (CDCl3) 4.08 (2H, m), 2.53 (1H, m), 2.46 (1H, m), 1.92 (4H, m), 1.70 (4H, m), 1.61 (2H, m), 1.38 (2H, m), 0.93 (3H, t, J 7 Hz). The mixture was cooled to ambient temperature The supernatant solution was decanted away from the resin The resin was washed with ethyl acetate: hexane (1:1, five 150 ml portions) the washings were added to the supernatant The solution was evaporated under reduced pressure the resulting residue diluted with toluene (25 ml) evaporated under reduced pressure dried

実験手順: A mixture of palladium chloride [27 mg, 0.15 mmol] and CuCl2 [41 mg, 0.30 mmol] in dioxane (10 ml) was stirred under carbon monoxide for 5 minutes. Then n-butyl formate (4 ml), 1-decene [0.75 g, 5.35 mmol] and aqueous hydrochloric acid (0.1 ml) were added and CO/O2 (1:1) was bubbled through the solution at room temperature and atmospheric pressure for a period of 24 hours. Analysis of the product gave n-butyl 2-methyldecanoate and n-butyl undecanoate with respectively 87% and 13% selectivity with a 64% conversion of the formic acid ester. CO/O2 (1:1) was bubbled through the solution at room temperature atmospheric pressure for a period of 24 hours

実験手順: In a tubular reactor, there was packed 10 ml. of a 0.5 wt.% palladium chloride-on-alumina catalyst, followed by introduction of a gaseous mixture consisting of 30.0% by volume of carbon monoxide, 3.2% by volume of hydrogen, 1.8% by volume of n-butyl nitrite and 65.0% by volume of nitrogen at a rate of 38 l. per hour to subject the gaseous mixture to reaction at a reaction temperature of 120° C. under ambient pressure. According to a gas-chromatographic analysis of the reaction mixture, it was found that n-butyl formate was produced in a space time yield of 65 g./l.-catalyst.hr and small amounts of di-n-butyl oxalate and n-butanol were by-produced. In a tubular reactor, there was packed per hour to subject the gaseous mixture to reaction at a reaction temperature of 120° C. under ambient pressure was produced in a space time yield of 65 g
