Description
本実施例では、Ni(II)配位触媒の合成について説明する。式IVの化合物を以下のようにして式IIIの化合物に変換した。化合物IV(8mmol)をNaBArF 4(8mmol)及びメシチレン(20mmol)と、100mlシュレンクチューブ内40mlジエチルエーテル中で混合し、−78℃に冷却した。5分後、ジエチルエーテル中1Mのアリルマグネシウムブロミド8mlを撹拌下で滴加した。アリルマグネシウムブロミドの添加完了後、冷却浴を交換することにより、温度を−20℃に上げた。−20℃で60分後、冷却浴を取り除き、混合物を25℃に温めた。この温度でエーテルは蒸留除去され、粗固体が残った。次に、塩化メチレン(30ml)を加え、混合物を撹拌した後、固体をろ過した。ヘプタン(10mL)を塩化メチレン溶液に加え、得られた混合物を高真空下で濃縮乾固し、Niベースの式IIIの触媒を約50%の収率で含有する固体6.85gを得た。
これらの実施例では、1,3−ブタジエン及びイソプレンと、2−(3−(トリエトキシシリル)プロピル)−1,3−ブタジエンとの共重合について説明する。官能性モノマーの2−(3−(トリエトキシシリル)プロピル)−1,3−ブタジエンは、Sunadaら(Journal of Applied Polymer Science,Vol.97,1545-1552(2005))に記載の方法に従って合成した。

本実施例では、イソプレンと、1−(E)−(トリエトキシシリル)−3−メチル−1,3−ブタジエン、1−(Z)−(トリエトキシシリル)−3−メチル−1,3−ブタジエン、及び2−(トリエトキシシリル)−3−メチル−1,3−ブタジエンの1:1.13:9.3混合物との共重合を示す。前記官能性モノマーの混合物は、Trostら(Journal of the American Chemical Society,Vol 123,12726−12727,(2001))に報告されているのと類似の手順を使用することにより、触媒量のトリス(アセトニトリル)ペンタメチルシクロペンタジエニルルテニウム(II)ヘキサフルオロホスフェートの存在下、2−メチル−ブタ−エン−3−インとトリエトキシシランとの反応により得られた。
