Summary: Main group carbonyl analogues derived from p-block elements have long been considered elusive. The recent isolation of acid-base free main group carbonyl analogues marked a new era, offering exciting new chemistry opportunities with their unperturbed nature. The emerging reactivity profiles of these derivatives highlight potential crossover reactivity with carbon and transition metal oxo species.

Summary: Metallocenes with interlinked cyclopentadienide ligands, also known as ansa-metallocenes or metallocenophanes, can have drastically different properties than their unbridged parent compounds. This concept is not limited to transition metals, but can also be applied to many main-group elements. This review focuses on recent advances in synthesis, structure, and properties of metallocenophanes based on group 2, group 13, group 14, and group 15 main-group elements.

Summary: This study reports on planar bismuth complexes with geometric Lewis acidity that can be tuned by varying the triamide ligand. The structures of these complexes were investigated in both solid and solution phase, revealing multiple modes of intermolecular association. The complexes showed comparable Lewis acidity to triarylboranes, but with the added ability to bind two bases simultaneously and reduced discrimination against soft substrates. Moreover, they demonstrated high catalytic efficacy in the ring opening polymerization of cyclic esters, suggesting their potential as less toxic alternatives to tin catalysts in medical grade material production.

Summary: This study provides a detailed investigation on the properties of phosphaphthalimide (1) and discovers the presence of pi-delocalization between 1 and neighboring carbonyl groups. Sodium salts of 1 were successfully synthesized using a modified procedure, and it was found that 1 exhibits good electrophilicity with the essential role of pi-delocalization in controlling its ambident properties.

Summary: In contrast to the extensive research on transition metal carbonyl complexes, the study of carbonyl complexes of main-group elements has only recently begun. Several carbonyl complexes of main-group elements have been reported, possessing various structures and bonding types as neutral, anionic, or cationic species, or as CO complexes on different surfaces. These complexes offer new possibilities in synthetic and catalytic chemistry, and contribute to our understanding of chemical bonding. Vibrational studies, especially the recording of infrared spectra, have played a crucial role in verifying the preparation and determining the structures of these often-unstable complexes. Theoretical calculations have also been used to assign vibrational spectra and predict the structures and stabilities of hypothetical complexes.

Summary: Since the discovery of phenyl azide in 1864, various organic azides have been developed and extensively studied. Azides have found applications as building blocks in organic synthesis, bioorthogonal chemistry, and materials science due to their amenability to a range of reactions. This review summarizes the reactions of main group compounds with azides and focuses on their reaction patterns and mechanisms.

Summary: The detection of energy conversion pathways between photons, charge carriers, and the lattice is crucial for understanding fundamental physics and advancing materials and devices. Attosecond core-level x-ray absorption fine-structure spectroscopy (XANES) provides a clear and simultaneous view of the temporal evolution of the photon-carrier-phonon system, revealing surprising new results. By applying this method to graphite, complex mechanisms involving electrons, holes, and optical phonons were elucidated, showcasing the utility of core-level XANES with attosecond temporal resolution for studying energy flow inside materials.

Summary: In this study, a diglyme solution of Na[cyclo-P-5] was reacted with alkynes and isolobal nitriles and phosphaalkynes to obtain (aza)phospholide anions 2 a-c, 4 a,b, and 6. The coordination of these anions with Fe-II resulted in the formation of (aza)phosphametallocenes 3 a-c, 5 a,b and 7. The new compounds were characterized using various spectroscopy and crystallography techniques.

Summary: In this study, a 3-amino-functionalized phosphabenzene compound was synthesized and structurally characterized. It was found that this compound exhibited some basic character and could be protonated by HCl. Unlike pyridines, this compound underwent a selective ring contraction in the presence of additional water. A rational mechanism for this unknown conversion was proposed based on experimental evidence and quantum chemical calculations.

Summary: Metal-ligand cooperativity (MLC) is a powerful approach to achieve new chemical transformations with metal complexes by leveraging reactive ligands. However, quantifying the effect of ligand modifications on MLC binding strength remains a challenge. In this study, cyclic voltammetry (CV) was used to quantify the differences in MLC binding strength in a series of square-pyramidal Ru complexes.

Summary: The synthesis and reactivity of an ambiphilic iridium complex with a chelating nontrigonal phosphorus triamide ligand are reported. The complex achieves a two-site oxidative addition of phenol through the cooperation of a Lewis basic iridium and a Lewis acidic phosphorus. Reactions with benzenethiol and benzeneselenol proceed via metal-centered oxidative addition.

Summary: The homogeneous catalysis of epoxide hydrogenolysis to give alcohols has been extensively studied. Catalyst systems have been developed for the selective formation of either branched or linear alcohol products. The proposed mechanisms of epoxide ring-opening involve cooperative C-O bond hydrogenolysis, but a new study suggests that the previously proposed bifunctional pathway is energetically inaccessible for ruthenium catalysts.

Summary: The study demonstrates that the ruthenium catalyst for ester hydrogenation is activated through dehydroalkylation of the pincer ligand, supporting a proposed catalytic mechanism involving the NHEt-substituted derivative. Experimental results show a first-order dependence on ruthenium and hydrogen concentrations, saturation behavior in ester concentration, and inhibition by the product alcohol. The findings are in good agreement with DFT calculations and crystallographically characterized catalytic intermediates.
