The reaction of the diborabenzene (DBB) nickel(0) pogo-stick complex [(η-DBB)Ni(CO)] () with a large excess of [Ni(CO)] yields the dark green, unstable dinickel(0) complex [(η-DBB)Ni(μ-CO)Ni(CO)] (), which loses one CO ligand to yield the purple, bimetallic Ni half-sandwich complex [(η-DBB)Ni(μ-CO)(η-CO)] (). The addition of the chromium aminoborylene complex [(OC)Cr{BN(TMS)}] (TMS = trimethylsilyl) to does not result in the expected borylene transfer but in the formation of the black Ni-Cr complex [(η-DBB)Ni(μ-CO)Cr(CO)] (), alongside the dimeric iminoborane [(TMS)BN(TMS)] (), which results from the rearrangement of the released BN(TMS) aminoborylene moiety. Furthermore, the oxidative addition of methyl triflate (MeOTf) to leaves the (η-DBB)Ni moiety intact and provides the ionic Ni half-sandwich complex [(η-DBB)NiMe(CO)]OTf (), while reaction with pentaphenylborole (PPB) yields the unique, dark-blue, unsymmetrical sandwich complex [(η-DBB)Ni(μ-CO)(η-PPB)] ().

Article Synopsis
- α-Fluoro-α'-aryl ketones are important compounds in the fields of pharmaceuticals and agrochemicals, but their synthesis can be challenging, especially for unsymmetrical versions.
- This study introduces a one-pot method for synthesizing these compounds using a combination of ynamide, aryl boronic acid, and a fluorine source under palladium (Pd) catalysis.
- The researchers conducted control experiments and DFT studies to propose a reaction mechanism that includes the formation of acetic acid during the process.
Side-On Bound Beryllium Dinitrogen Complex: A Precursor for Complete Conversion of Dinitrogen to Ammonia Mediated by -Heterocyclic Carbene.

The complete conversion of dinitrogen to ammonia mediated by a side-on N-bound carbene-beryllium complex, [NHC-Be(η-N)] has been studied considering both the symmetric and unsymmetric pathways. -heterocyclic carbenes complexed with Be(η-N) moieties were considered substrates in our study. We found that two mechanistic pathways were possible for the reduction of dinitrogen to form ammonia.

Organic compounds with 1,3-diketone or 3-amino enone functional groups are extremely important as they can be converted into a plethora of carbo- or heterocyclic derivatives or can be used as ligands in the formation of metal complexes. Here, we have achieved the preparation of a series of non-symmetrical β-ketoenamines (O,N,N proligand) of the type (4-MeOCH)C(=O)CH=C(R)NH(Q) obtained through the Schiff base condensation of 1,3-diketones (1-anisoylacetone, 1-anisyl-3-(4-cyanophenyl)-1,3-propanedione, and 1-anisyl-3-(4,4,4-trifluorotolyl)-1,3-propanedione) functionalized with electron donor and electron-withdrawing substituents and 8-aminoquinoline (R = CH, 4-CHCN, 4-CHCF; Q = CHN). Schiff base ketoimines with a pendant quinolyl moiety were isolated as single regioisomers in yields of 22-56% and characterized with FT-IR, H NMR, and UV-visible spectroscopy, as well as single-crystal X-ray crystallography, which allowed for the elucidation of the nature of the isolated regioisomers.

This study highlights the importance of developing sensitive and selective sensors for use in pharmaceutical applications for the first time. A novel iron(III)-complex, constructed from unsymmetrical tetradentate NNN'O type Schiff base ligand (E)-3-((6-aminopyridin-2-yl)imino)-1-phenyl butane-1-one (LH) and its structure of it characterized by using various spectroscopic techniques such as FT-IR, UV-Vis, elemental analysis, conductivity, magnetic susceptibility measurements and the TGA method. The correlation of all results revealed that the coordination of the (LH) with the metal ion in a molar ratio of 1:1 leads to the formation of an octahedral geometry around the metal ions.
