参考标题:Synthesis Of Substituted Anilines From Cyclohexanones Using Pd/c-Ethylene System And Its Application To Indole Synthesis 作者:Katsumi Maeda,Ryosuke Matsubara,Masahiko Hayashi |发布日期:2021.3.5 摘要:The Synthesis Of Anilines And Indoles From Cyclohexanones Using A Pd/c-Ethylene System Is Reported. A Simple Combination Of Nh4Oac And K2Co3 Under Nonaerobic Conditions Was Found To Be The Most Suitable To Perform This Reaction. Hydrogen Transfer Between Cyclohexanone And Ethylene Generates The Desired Products. The Reaction Tolerates A Variety Of Substitutions On The Starting Cyclohexanones.
