Alkene Hydrogenations by Soluble Iron Nanocluster Catalysts

et al. 2017

The replacement of noble metal technologies and the realization of new reactivities with earth-abundant metals is at the heart of sustainable synthesis.Alkene hydrogenations have so far been most effectively performed by noble metal catalysts. This study reports an iron-catalyzedh ydrogenation protocol for tri-and tetra-substituted alkenes of unprecedented activity and scope under mild conditions (1-4 bar H 2 ,2 08 8C). Instructive snapshots at the interface of homogeneous and heterogeneous iron catalysis were recorded by the isolation of novel Fe nanocluster architectures that act as catalyst reservoirs and soluble seeds of particle growth.

Alkene hydrogenations have so far been most effectively performed by noble metal catalysts. This study reports an iron‐catalyzed hydrogenation protocol for tri‐ and tetra‐substituted alkenes of unprecedented activity and scope under mild conditions (1–4 bar H2, 20 °C). Instructive snapshots at the interface of homogeneous and heterogeneous iron catalysis were recorded by the isolation of novel Fe nanocluster architectures that act as catalyst reservoirs and soluble seeds of particle growth.

We report a new family of nickel phosphinidene molecular clusters synthesized from the reaction of bis(1,5‐cyclooctadiene)nickel(0) ([Ni(cod)2]) with organocyclophosphine and trialkylphosphine. We found that [Ni(cod)2] cleaves the organocyclophosphine P−P bonds to generate phosphinidene groups, establishing the cyclic molecules as valuable precursors for making charge‐neutral molecular clusters passivated by two‐electron donor capping ligands. The formation of the cluster core structure is controlled by the bulkiness of the precursor and of the capping ligand. As a demonstration of this new cluster‐forming reaction, we describe three clusters with different core nuclearity and degree of ligation: Ni12(PMe)10(PEt3)8, Ni8(PMe)6(PMe3)8, and Ni8(PiPr)6(PMe3)6. In addition, we show that the larger cluster, Ni12(PMe)10(PEt3)8, can be used as a low temperature single‐source molecular precursor to the catalytically active nickel phosphide phase Ni2P.
