Abstract Tetranuclear Ga(III) complexes L 1–3 2 Ga 4 ( t ‐Bu) 8 1 – 3 are synthesized and characterized (elemental analysis, IR, H, 13 C, DOSY NMR spectroscopy, XRD) their activity in the ring‐opening polymerization (ROP) of lactide (LA) ϵ‐caprolactone ϵ ‐CL) is reported. Complex most active homopolymerization catalyst presence benzyl alcohol (BnOH), yielding isotactic‐enriched polylactides (PL...

This article provides an overview of the rich chemistry rhenium and manganese decacarbonyls, M2(CO)10 (M = Re, Mn) their acetonitrile derivatives [M2(CO)8(NCMe)2] as precursors for synthesis new di‒, tri‒ tetranuclear complexes derived from a wide range heterocyclic thiols such pyridine-2-thiol, pyrimidine-2-thiol, tetrahydropyrimidine-2-thiol, 2-mercapto-1-methylimidazole, benzimidazole-2-thio...

By employing the HSAB principle and “assisted self-assembly” approach using 2-pyridylaldoximate (pao−) as primary ligand pivalate (piv−) ancillary co-ligand, tetranuclear [CoIII2LnIII2(NO3)4(pao)4(piv)4] complex polynuclear compounds were isolated (Ln = Dy, Gd, Tb, Pr, Y). The structure of Dy(III) was determined via single-crystal X-ray crystallography, revealing a metal topology two {CoIIIDyII...

Metalation of N-mesityl-P,P-diphenylphosphinic amide with nBuLi in toluene yields tetranuclear lithium N-mesityl-P,P-diphenylphosphinimidate ([Ph2P(OLi)=N−Mes]4, 1). Ph2P(O)−N(H)Mes a mixture dibutylmagnesium and butyllithium DME leads to formation dinuclear [Ph2P{OLi(dme)}=N−Mes]2 (2). Excess gives [Li(O−PPh2=N−Mes){Ph2P(=O)−N(H)−Mes}]2 (3) three-coordinate alkali ions. The metathetical approa...
