Iron is the most abundant transition metal in Earth, s crust; it is relatively inexpensive, not
very toxic, and environmentally benign. 1 Undoubtedly, due to the involvement in a multitude …

Conspectus Asymmetric transition metal catalysis is an indispensable tool used both in
academia and industry for forging chiral molecules in an enantioselective fashion. Its …

Strongly σ‐donating N‐heterocyclic carbenes (NHCs) have revived research interest in the
catalytic chemistry of iron, and are now also starting to bring the photochemistry and …

A new iron aziridination catalyst supported by a macrocyclic tetracarbene ligand has been
synthesized. The catalyst,[(Me, EtTC Ph) Fe (NCCH3) 2](PF6) 2, was synthesized from the …

Chirality is an essential feature of asymmetric catalysts. This review summarizes asymmetric
catalysts that derive their chirality exclusively from stereogenic metal centers. Reported …

Although iron has been known and widely used in coordination and organometallic
chemistry for decades and N‐heterocyclic carbenes (NHCs) have also been used for about …

A novel ruthenium catalyst is introduced which contains solely achiral ligands and acquires
its chirality entirely from octahedral centrochirality. The configurationally stable catalyst is …

Ruthenium (II) p-cymene complexes with picolyl-functionalized N-heterocyclic carbenes [(η6-
p-cymene) Ru (L)(Cl)][PF6](L= 3-methyl-1-(2-picolyl) imidazol-2-ylidene (1a), 3-isopropyl-1 …

Analogues of [Ru (bpy) 3] 2+ were prepared in which one pyridine ligand site is substituted
by a N-heterocyclic carbene (NHC) ligand, that is, either by an imidazolylidene with a …

A new class of chiral iron catalysts is introduced that contains exclusively achiral ligands
with the overall chirality being the result of a stereogenic iron center. Specifically, iron (II) is …
