Rapid Intermolecular C-H Activation of Aromatic Substrates at a Cationic, Electrophilic Molybdenum (VI) Nitrido Complex: Mechanistic Nuance in C-H Amination Open
When the cationic, octahedral terminal nitrido complex of Mo(VI) supported by a diborate pentadentate ligand is generated in the absence of trapping nucleophiles, it rapidly activates the C(sp2)-H bonds of simple arenes to form the cationi…

Rapid and selective formic acid dehydrogenation catalysis by molecular ruthenium hydrides supported by rigid PCcarbeneP pincer ligands Open
A series of four molecular ruthenium hydrido complexes supported by previously reported rigid PCcarbeneP pincer ligand frameworks were evaluated as formic acid dehydrogenation (FAD) catalysts. The ligands in the complexes LRRu(H)X (R = H, …

Nucleophilic and Electrophilic Molybdenum Terminal Oxo Complexes By Coordination-Induced Bond Weakening of Hydroxo O-H Bonds. Open
The extent of coordination-induced bond weakening in aquo and hydroxo ligands bonded to a molybdenum(III) center complexed by a dianionic, pentadentate ligand system was probed by reacting the known complex (B2Pz4Py)Mo(III)-NTf2, I, with d…

Direct C-H Electrophilic Borylation with (C6F5)2B-NTf2 to Generate B-N Dibenzo[a,h]pyrenes Open
The borylation of aryl substituted pyridines is an effective way of preparing B-N doped conjugated organic frameworks. Trihaloborane Lewis acids are often employed for this protocol, and may require further functionalization to replace the…

Oxidation-induced ambiphilicity triggers N–N bond formation and dinitrogen release in octahedral terminal molybdenum(<span>v</span>) nitrido complexes Open
N–N bond formation in octahedral, terminal d 1 Mo( v ) nitridos to give μ-dinitrogen complexes requires one eletron oxidation with 0.5 equivalents of oxidant to open a kinetically feasible ambiphilic nitrido coupling pathway.

Ruthenium polyhydrides supported by rigid PCP pincer ligands: dynamic behaviour and reactions with CO2 Open
Two rigid beta-elimination immune PCcarbeneP pincer ligands, differing in their electron donor properties by variation of the substitution pattern on the aromatic linker arms, were complexed to ruthenium to form the dichlorides LRRuCl2 (R …
