Cyclometalated Platinum β-Diketiminate Complexes
… platinum complexes with ancillary β-diketiminate (NacNac) ligands, prepared by a general synthetic route are described. Two different cyclometalating (C^N) ligands―2-phenylpyridine (ppy) and 2-(2,4-difluorophenyl)pyridine (F2ppy)―are used in concert with two different fluorinated …

Exploiting cooperative effects in s-Block organometallics for new applications in synthesis and catalysis
… the same molecule a sterically demanding β-diketiminate ligand with a kinetically activatedTMP base [DippNacnacMg(TMP)], regioselective magnesiation of heterocyclic and aromatic molecules, including pyrazine or 1,2,4,5-tetrafluorobenzene, can be achieved at room temperature. Structural …

Metals in Chemistry and Biology: Computational Chemistry Studies
… The T-shaped geometry of a three-coordinate β-diketiminate nickel(I) complex with a CO ligand was compared and contrasted with isoelectronic and isosteric copper(II) complexes. (4) Glutathione synthetase (GS), an enzyme that belongs to the ATP-grasp superfamily, catalyzes the (Mg, …

Development of Iridium Based Photosensitizer for Potent Photoreductants and Photocatalytic Application
… iridium photoreductants with electron-rich β-diketiminate (NacNac) ligands. The photophysical and electrochemical properties were compared to fac-Ir(ppy)3, known to be a ‘the-state-of-the-art’ photoreductant, and the calculated excited-state potentials (ESPs) show that our complexes have more …

Development of magnesium aluminate and gallate chemistry incentivised by potential in rechargeable battery technology
… emanating for the dication. By using a β-diketiminate ligand, the magnesium cation [(DippNacnac)Mg*2THF]+ was created, reducing the opposite charge attraction to give a soluble complex. These synthetic advances, alongside preliminary battery tests, give an insight into where the problems …

Reactivity of a Low Valent Gallium Compound
… is conducted to expand the reactivity of the β-diketiminate gallium(I) compound, NacNacGa (NacNac=[ArNC(Me)HC(Me)NAr]−, Ar=2,6-iPr2C6H3). The reactivity of NacNacGa towards various unsaturated compounds is studied. In particular, reaction between NacNacGa and phenyl isothiocyanate resulted in …

Reactivity of Aluminum Carbenoid with Unsaturated Substrates
Reactivity patterns of the β-diketiminate aluminum(I) complex NacNacAl towards a variety of unsaturated molecules were determined. Reaction of NacNacAl with one equivalent of benzophenone affords η2(C,O) adduct III-2 that undergoes cyclization reactions with benzophenone (III-3), aldimine (III-4), …

Synthesis and Reactivity of Low Valent Main Group Element Complexes
The β-diketiminate aluminum(I) complex NacNacAl (III-1) was shown to activate a range of substrates containing robust single and double bonds. Compound III-1 oxidatively adds a variety of H–X bonds (X = H, B, Al, C, Si, N, P, O) to give a series of four-coordinate aluminum hydride derivatives …
