ヒドロホルミル化の触媒としての上述した錯体の使用。
本発明は、以下、実施例によって詳細に説明される。
バイアルにPtX2(X=ハロゲン)、リガンド、およびオーブンで乾燥させたスターラーバーを入れた。バイアルを、セプタム(PTFEコーティングスチレン-ブタジエンゴム)とフェノール樹脂キャップで密閉した。バイアルを排気し、アルゴンを3回再充填した。シリンジを使用して、トルエンおよび１－オクテンをバイアルに添加した。バイアルを合金板に入れ、これをアルゴン雰囲気下でパー・インスツルメント社の４５６０シリーズのオートクレーブに移した。オートクレーブをCO/H2で3回パージした後、合成ガスの圧力を室温で40バールに上げた。反応は８０℃で１８時間行った。反応が終了したら、オートクレーブを室温まで冷却し、注意深く減圧した。収率および選択性はＧＣ分析によって決定した。
