“…Another specific approach, is the ring opening with phenyllithium of the strained 1-phenyl-1-phospha-[1]-ferrocenophane 6, which can be obtained from the corresponding 1,1′-dilithiated ferrocene 1 (Scheme 2) [22][23][24][25]. When this compound is now reacted with N,Ndimethylformamide, the corresponding phosphane ferrocenecarbaldehyde 8 is formed.…”

Due to their unique steric and electronic properties, air-stability and modular structure, chiral hybrid P,N-ferrocenyl ligands play a prominent role in the field of asymmetric catalysis. This report aims to give a concise introduction to the syntheses of chiral hybrid P,N-ferrocenyl ligands and presents an overview of their application in enantioselective catalysis. This review is of special interest to chemists working on ligand design and asymmetric catalysis, as well as to the broader organic and inorganic community.

“…In the absence of these factors, there is no inherent weakening of the metalring bonding upon tilting, exemplified by a comparison of how the calculated total energy of both [ 2 ) vary with the bending angle a (Figure 2). When all three HOMO orbitals are fully occupied, as in the case of a d 6 configuration for iron, the total energy of the molecule is raised significantly upon ring tilting. As a result, ferrocene shows a strong preference for a parallel ring arrangement.…”

“…Thermal as well as nucleophile-assisted and cationic ROP can lead to polyferrocenylstannanes, emphasizing the reactivity of the C ipso ÀSn bond. [27,77] Unlike the more highly tilted boron-bridged [1] [6] and by Seyferth and Withers, Jr. [7] Most known derivatives to date bridged by phosphorus and arsenic have been prepared by the versatile reaction of dilithioferrocene(tmeda) with Group 15 organodihalides. [102] In some cases, the use of enantiomerically resolved dichloroorganophosphines has allowed access to chiral phosphorusbridged [1]ferrocenophanes.…”

“…[6][7][8] The unusual structures, reactivity, and potential utility of strained metallocenophanes and related species, such as metalloarenophanes (for example, 3; E = main-group element), have led to extensive recent developments in the area. The discovery in the early 1990s that strained ferrocenophanes undergo ROP to yield high-molecular-weight polyferrocenes [Eq.…”

The structures, bonding, and ring-opening reactions of strained cyclic carbon-based molecules form a key component of standard textbooks. In contrast, the study of strained organometallic molecules containing transition metals is a much more recent development. A wealth of recent research has revealed fascinating nuances in terms of structure, bonding, and reactivity. Building on initial work on strained ferrocenophanes, a broad range of strained organometallic rings composed of a variety of different metals, pi-hydrocarbon ligands, and bridging elements has now been developed. Such strained species can potentially undergo ring-opening reactions to functionalize surfaces and ring-opening polymerization to form easily processed metallopolymers with properties determined by the presence of the metal and spacer. This Review summarizes the current state of knowledge on the preparation, structural characterization, electronic structure, and reactivity of strained organometallic rings with pi-hydrocarbon ligands and d-block metals.
