Abstract

Herein we demonstrate the use of ethylenediamine bisborane (EDAB) as a suitable hydrogen source for transfer hydrogenation reactions on C-C double bonds mediated by metal nanoparticles. Moreover, EDAB also acts as a reducing agent for carbonyl functionalities in water under metal-free conditions.

Highlights

  • Hydrogenation is one of the most important chemical transformations used in academia and industry and has received notable attention in the past century [1,2,3,4,5,6,7]

  • Have been used as suitable hydrogen sources in transfer hydrogenation reactions. Many of these transformations can be performed by using homogenous catalysis with transition metal complexes based on iron, palladium, ruthenium, or rhodium [4,7,15,17,20,21]

  • We focus on the use of ethylenediamine bisborane (EDAB) as a possible hydrogen source for transfer hydrogenation reactions

Summary

Introduction

Hydrogenation is one of the most important chemical transformations used in academia and industry and has received notable attention in the past century [1,2,3,4,5,6,7]. Amine boranes have been used as possible hydrogen storage material These non-toxic and water-soluble compounds have shown successful use as hydrogen sources for transfer hydrogenation reactions. Our group has investigated the liberation of H2 from EDAB in ionic liquid media as a potential hydrogen storage material [26,31]. Following these studies, we focus on the use of EDAB as a possible hydrogen source for transfer hydrogenation reactions. The use of EDAB as a suitable hydrogen source in transfer hydrogenation reactions is unknown
