1-Phenylethylamine (2). To a Schlenk vessel containing [RhCp*Cl2]2 (257 mg, 416 mmol) and HCOONH4 (26.2 g, 416 mmol) was added 9.71 mL (83.2 mmol) of acetophenone 1. The brown mixture was frozen, evacuated and stirred for 7 h at 70 ℃. To the green solution at r.t. was added 160 mL of 1M aq HCl. The mixture was washed twice with DCM (20 mL) and 15 mL of cold 12M NaOH was added. The aq layer was extracted with 6 x 50 mL of DCM, dried and evaporated in vacuo to give crude 2 (9.3 g, 92%) which was distilled at 83 ℃/44 mm to afford 2 (8.6 g, 85%).【J. Org.

Leuckart (1854-1889)生于德国吉森, 后来师从于 Bunsen, Kolbe, 和von Baeyer,称为哥根廷大学副教授,可惜在35岁意外死亡,对于化学界是巨大的损失。Otto Wallach (1847-1931)生于普鲁士的哥尼斯堡,师从于Wöhler 和 Hofmann。在1889年到1915年出任哥根廷大学化学研究所大学主任。他所著的《萜烯和樟脑》为后来萜烯化学奠定了基础。Wallach由于在脂环化合物方面的研究获得了1910年的诺贝尔化学奖。相关文献1.
