Coordination Behaviour of 1-(4,2′:6′,4′′-terpyridin-4′-yl)ferrocene and 1-(3,2′:6′,3′′-terpyridin-4′-yl)ferrocene: Predictable and Unpredictable Assembly Algorithms

“…[4] The incorporation of ferrocenyl-units also allows the development of promising properties for applications including photoinduced electron transfer, [5] electrochemical sensing [6] and enhanced stability and reactivity in palladium based catalysts for cross-coupling reactions. [7,8] Scheme 1. Examples of mono-and disubstituted ferrocenyl ligands used for the assembly of discrete complexes and coordination polymers.…”

“…Functionalization of one cyclopentadienyl ring typically leads to ligands suited to the formation of discrete complexes, [9,10] and the chiral ligand at the top-right of Scheme 1 is of note for its use in giving enhanced stability and crystallization behaviour in palladium complexes utilized in cross-coupling reactions. [8] Functionalization of both cyclopentadienyl rings with donor groups produces potential linkers in multinuclear assemblies including metallocycles and coordination polymers. [11] On the one hand, the conformational flexibility of the ferrocenyl unit through independent rotation of the Cp rings about the iron atom "ball-bearing" endows 1,1'-substituted ferrocenes with a degree of freedom facilitating the assembly of diverse architectures.…”

Chiral Diphosphine ddppm‐Iridium Complexes: Effective Asymmetric Imine Hydrogenations at Ambient Pressures

“…[5,6] This catalyst is used industrially for the synthesis of a key intermediate to the herbicide (S)-Metolachlor. Pfaltz et al have used a phosphino-oxazoline system obtaining up to 89% ee.…”

Enantioselective Synthesis of Alcohols and Amines by Iridium‐Catalyzed Hydrogenation, Transfer Hydrogenation, and Related Processes

“…[30] They hypothesized that catalyst deactivation took place by irreversible formation of an inactive dimeric species (29) (Scheme 8a), similar to the dimers observed by Crabtree during the hydrogenation of alkenes. [31] They proposed two solutions to suppress the formation of the inactive species.…”
