Synthesis and Reactivity of Substituted Phosphanylalanes and ‐Gallanes Stabilized by N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, EarlyView.
A series of NHC‐stabilized phosphanylalanes and phosphanylgallanes bearing alkyl and aryl substituents at phosphorus was synthesized and characterized. Structural and computational studies reveal how substitution influences E13─P bonding and phosphorus donor properties, while reactions with BH3 demonstrate the accessibility of the phosphorus lone pair ...

Alkali Metal Mediated Redox Tuning in Bis(μ‐OH) Dinickel(II) Complexes

open access: yesChemistry – A European Journal, EarlyView.
Alkali metal ions are ubiquitous in both enzymatic and synthetic catalytic media. The present study highlights the powerful influence common monocations have on the structural and electrochemical properties of catalytically relevant bis(μ‐hydroxo) dinickel diamond cores, through a well‐defined series of heterometallic clusters (Li+, Na+, K+, and Cs ...

Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

open access: yesEcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

2.1.2 Ring-Closing Metathesis

open access: yes, 2018
This chapter describes the use of ruthenium alkylidene complexes bearing N-heterocyclic carbene ligands as catalysts for the preparation of cyclic compounds (from 5- to 33-membered rings) by metathesis. Also included are examples of asymmetric metathesis
