Abstract

Abstract: We present herein the catalytic hydrogenation of various urea derivatives to amines and methanol. The reaction is catalyzed by a ruthenium or an iridium Macho pincer complex and produces amine and methanol in very good to excellent yields. Moreover, we also expand this concept to demonstrate the first example of the hydrogenative depolymerization of polyureas to produce diamines and methanol in moderate yields. Abstract : Hydrogenation of various urea derivatives and polyureas to amines/diamines and methanol using ruthenium and iridium Macho‐pincer catalysts is reported herein. Considering that the reverse reaction has been reported before, the present study is of significance to the circular economy, methanol economy, and hydrogen economy (development of liquid hydrogen storage material).
