Improved Ruthenium‐Catalyzed Amination of Alcohols with Ammonia: Synthesis of Diamines and Amino Esters

Diamination of diols: The first homogeneously catalyzed diaminations of primary and secondary diols with ammonia give the corresponding diamines. Other primary as well as secondary alcohols including hydroxy-substituted esters can also be efficiently converted to primary amines. This atom-efficient and selective amination method proceeds in an ammonia atmosphere without additional hydrogen sources.
