    Abstract: 中 文 摘 要 氮取代之異吲哚啉可在鈀金屬催化下還原氫化為四氫異吲哚,並且有不錯的產率。藉由氫之同位素標定來探究其反應機制,同時也發現有氫/氘交換的反應產生,並且驗證芳香性在此反應中是必要的。吲哚啉也可在鈀金屬催化下轉換為吲哚。 Abstract The high-yield syntheses of 4,5,6,7-tetrahydro-isoindoles from N-substituted isoindolines under palladium catalyzed hydrogenation conditions are reported. Mechanistic study with deuterated and saturated substrates shows extensive H/D exchange and the essence of aromaticity in this transformation. Indolines can also transform to indoles under palladium catalyzed hydrogenation conditions.
