Journal ArticleDOI
Di- and tri-valent chlorochromium complexes bearing hydrotris(3,5-diisopropylpyrazolyl)borato ligand (TpiPr2), TpiPr2CrCln(L) (n = 1, 2) and [TpiPr2Cr(μ-Cl)]2: flexible coordination behavior of the TpiPr2 ligand and reduction features of Cr(II) species
TL;DR: In this paper, the TpiPr2 ligand has been used to obtain a variety of coordination geometries including five-coordinate square pyramidal and trigonal-bipyramidal structures.
Journal ArticleDOI
Synthesis and structural characterization of a new class of organoborato ligands containing imidazolyl functional groups [MeB(ImN-Me)2(X)]−
TL;DR: A series of alkylborate compounds containing imidazolyl functional groups [MeB(ImN-Me)2(X)]− (X ǫ = OPri1, Cl 2, Pz 3 or Ph 4) has been synthesized and characterized by X-ray crystallography.
Journal ArticleDOI

TL;DR: The nickel(II) complex reacts with O(2) to form the ligand oxygenation product ArSO(2)(-) in MeCN, and also 1a catalyzes the oxygenation of external substrates such as triphenylphosphine.
Journal ArticleDOI
Oxygenation of a low valent rhodium complex, TpiPr2Rh(dppe): sequential conversion of molecular oxygen into peroxo and hydroperoxo complexes and characterization of the peroxo species
TL;DR: In this paper, the TpiPr2Rh system was verified by isolation and characterization of the intermediates, and it was revealed that in the present N-rich coordination system, the basic peroxo ligands (O2, OOH) form hydrogen-bonding interactions with the proximal N and NH functional groups.
Journal ArticleDOI
Synthesis and dehydrative condensation of monomeric hydroxoruthenium complexes with hydrotris(3,5-diisopropylpyrazolyl)borate ligand, TpiPr2Ru(L2)-OH (L2 = dppe, bipy).
TL;DR: Monomeric neutral hydroxoruthenium complexes, TpiPr2RuOH(L2) (L2 = dppe, bipy), are prepared by deprotonation of aquo complexes, and it is confirmed that dehydrative condensation reaction of the hydroxo complexes with carboxylic acids involves protonated replacement of the resultant aquo ligand by the nucleophile.
