Transition metals form a variety of alkylidyne complexes with either a d0 metal center (high-
valent) or a non-d0 metal center (low-valent). One of the most interesting properties of …

Catalytic olefin metathesis based on the second‐and third‐row transition metals has
become one of the most powerful transformations in modern organic chemistry. The shift to …

Studies on N2 activation and transformation by transition metal hydride complexes are of
particular interest and importance. The synthesis and diverse transformations of a dinitrogen …

Terminal imide ligands in early-transition-metal chemistry have recently undergone a
dramatic renaissance, given their potential applications in processes such as group transfer …

Synthesis, characterization, and catalytic alkyne polymerization results for the first trianionic
pincer alkylidyne complex,[t BuOCO] W CC (CH3) 3 (THF) 2 (6), are described. Complex 6 …

Appending an amine to a C C double bond drastically increases the nucleophilicity of the β-
carbon atom of the alkene to form an enamine. In this report, we present the synthesis and …

We demonstrate that a titanium-carbon multiple bond, specifically an alkylidyne ligand in the
transient complex,(PNP) TiCtBu (A)(PNP−= N [2-P (CHMe2) 2-4-methylphenyl] 2), can …
