【0152】
ジカルボニル化合物の金属錯体は、次の合成スキームに従い、物質量X mmolのテトラキス[2−(2−ピリジニル)フェニル−N,C2’](μ−ジクロロ)ジイリジウム(III)と、2.2X mmolのジカルボニル化合物と、22X mmolの炭酸ナトリウムとを混合し、50X cmの2−エトキシエタノールを溶媒として用い、90℃で21時間、加熱・撹拌した後、室温まで冷却し、1000X cmの蒸留水を加えた。
【0153】
S01〜S31(次の表7〜表9中のEntry 1〜28)は、前記の蒸留水を加えた混合物から、析出した固体を濾過により取り出し、10X cmのメタノールを加えて洗浄し、次いで、100X cmのジエチルエーテルを加えて洗浄し、溶け残った固体を濾過により取り出して減圧乾燥し、表5に示すように、33〜93%の収率で得た。

また、S32,S33(次の表9中のEntry 29,30)は、前記の蒸留水を加えた混合物から、1000X cmのジクロロメタンで抽出し、さらにジクロロメタン層を500X cmの蒸留水で3回洗浄した。ジクロロメタン層を無水硫酸マグネシウムで乾燥後、ろ過し、ろ液を減圧留去した。得られた混合物を、酢酸エチル:ヘキサン=1:5の混合物を展開溶媒とするシリカゲルカラムクロマトグラフィー法によって精製し、更に、得られた固体に20X cmのジエチルエーテルを加えて洗浄し、溶け残った固体を濾過により取り出して減圧乾燥し、表9に示すように、40〜84%の収率で得た。尚、ここでは、物質量X mmol=0.10mmolとして行ったが、スケールを適宜変更して行っても良い。

The dichloromethane layer was dried over anhydrous magnesium sulfate and filtered, and the filtrate was distilled off under reduced pressure. The obtained mixture was purified by silica gel column chromatography using a mixture of ethyl acetate: hexane = 1: 5 as a developing solvent, and the obtained solid was further added to 20 × cm 2. 3 The diethyl ether was added and washed, and the undissolved solid was removed by filtration and dried under reduced pressure, and as shown in Table 9, it was obtained in a yield of 40 to 84%. Here, although the substance amount X mmol = 0.10 mmol was used, the scale may be changed as appropriate.
