Zhou, Qiwen Zhang, Lanqiong Meng, Wei Feng, Xiangqing Yang, Jing Du, Haifeng Borane-Catalyzed Transfer Hydrogenations of Pyridines with Ammonia Borane With the use of ammonia borane as a hydrogen source, a borane catalyzed metal-free transfer hydrogenation of pyridines was successfully realized for the first time to furnish a variety of piperidines in 44–88% yields with moderate to excellent <i>cis</i>-selectivities. The ease in handling without requiring high pressure H<sub>2</sub> makes this transfer hydrogenation practical and useful. ci;metal-free transfer hydrogenation;selectivitie;ammonia borane;piperidine;variety;transfer hydrogenation;Pyridine;Borane-Catalyzed Transfer Hydrogenations;Ammonia Borane;handling;pyridine;pressure H 2;yield;hydrogen source 2016-09-28
