Abstract
Description
一般式(1)におけるEとしては、置換あるいは無置換のアリール基、置換あるいは無置換の複素環基、置換あるいは無置換の縮合多環芳香族基または置換あるいは無置換の縮合多環複素環基などが挙げられる。
(イ)カップリング反応による方法
3,4−ジハロゲン化キノキサリンと、ボロン酸とを、鈴木カップリング反応させる事により、キノキサリン誘導体化合物を合成できる(合成スキーム1〜2を参照)。この方法は、対称型キノキサリン誘導体化合物の合成(合成スキーム1を参照)に用いられるだけでなく、非対称型キノキサリン誘導体化合物の合成(合成スキーム2を参照)に最適な方法である。
1,2−フェニレンジアミンと、ベンジル等の1,2−ジケトン化合物とを脱水縮合反応させる事により、キノキサリン誘導体化合物を合成できる(合成スキーム3を参照)。
上記の方法等により合成されたキノキサリン誘導体化合物と、塩化イリジウム(III)水和物等の金属塩化物とを反応させる事により、環状イリジウム化−クロロ架橋二量体化合物を合成できる(合成スキーム4を参照)。
上記の方法等により合成された環状メタル化―μ―クロロ架橋二量体と、2,4−ペンタンジオン等の1,3−ジカルボニル化合物とを反応させる事により、(1,3−ジオナト−κO,κO‘)有機金属化合物を合成できる(合成スキーム4を参照)。
合成スキーム5に示すように、上記の方法等により合成された(1,3−ジオナト−κO,κO‘)有機金属化合物と、キノキサリン誘導体化合物とを、グリセロール等の高沸点極性溶媒中で、加熱して反応させる事により、(1,3−ジオナト−κO,κO‘)部位が、キノキサリン誘導体化合物部位で置換され、3つのキノキサリン誘導体化合物の部位が金属に結合した構造を有する、トリス型有機金属化合物を合成できる。
