Protic pyrazoles (N-unsubstituted pyrazoles) have been versatile ligands in various fields,
such as materials chemistry and homogeneous catalysis, owing to their proton-responsive …

The chromium electrodeposition process produces functional chromium layers and high-
purity chromium metal, which are used in a wide range of industries. Compared with the …

N-alkylation and N-metallation of pyridine are explored herein to understand how metal-
ligand complexes can model NAD+ redox chemistry. Syntheses of substituted …

Reduction of the bis‐(pyrazolyl) pyridine complex [LCr] 2 with stoichiometric KC8 in THF
produces a species that is reactive with CO2 to produce an aggregate composed of …

Reaction of Cr [N (SiMe3) 2] 2 (THF) 2 with equimolar bis‐pyrazolylpyridine, H2L, yields a
product of empirical formula CrL. The kinetic product is [CrL] 2, which transforms into the …

We describe here delivery of hydrazine to a reducing, low oxidation state chromium bound
to a proton responsive ligand which has already been deprotonated. Reaction of PhHNNH2 …

Abstract Dimeric [CrL] 2, where L is the conjugate base of bis‐pyrazolyl pyridine, is
evaluated for its ability to undergo inner sphere and outer sphere redox chemistry. It reacts …

Reduction of the bis‐pyrazolyl pyridine complex [CrL] 2 with 4 KC8, followed by addition of
one azobenzene (overall mole ratio 1: 4: 1), PhNNPh, transfers reducing equivalents to …

The development of the Haber-Bosch process revolutionized the world in the early1900s;
however, the increased use of ammonia fertilizers has led to environmental and …
