Abstract Two new trinuclear μ 3 ‐bridged rare‐earth metal phosphinidene complexes, [{L(Ln)(μ‐Me)} (μ ‐Me)(μ ‐PPh)] (L=[PhC(NC 6 H 4 i Pr 2 ‐2,6) ] − , Ln=Y ( a ), Lu b )), were synthesized through methane elimination of the corresponding carbene precursors with phenylphosphine. Heating toluene solution at 120 °C leads to an unprecedented ortho CH bond activation PhP ligand form bridged phosphinidene/phenyl complexes. Reactions ketones, thione, or isothiocyanate show clear phospha‐Wittig...
Three kinds of solvated lithium amidinates with different coordination models were obtained via recrystallization [PhC(NC6H4iPr2-2,6)2]Li(THF) (1a) in solvents. Treatment o-Me2NC6H4CH2Li LLnCl2(THF)n (2; L = [PhC(NC6H4iPr2-2,6)2]− (NCNdipp), [o-Me2NC6H4CH2C(NC6H4iPr2-2,6)2]− (NCNdipp′)) formed situ from reaction LnCl3(THF)x LLi(THF) gave the rare-earth-metal bis(aminobenzyl) complexes LLn(CH2C6H4NMe2-o)2 (L NCNdipp, Ln Sc (3a), Y (3b), Lu (3c); NCNdipp′, (3d), (3e)) high yields.

Multifunctional additives are widely utilized in enhancing the performance of perovskite solar cells, and role is highly related to contained various functional groups. Here, we introduce a pair geometric isomers, which act as bifunctional with terminal −NH3+ group −COOH group, into methylammonium lead iodide perovskite. Surprisingly, although two share exactly same groups, find that they play opposite roles crystallization process. The systematical investigation indicates only trans...
Reactions of trinuclear rare-earth metal complexes bearing functionalized phosphinidene ligand [L3Ln3(μ2-Me)2(μ3-Me)(μ3-η1:η2:η2-PC6H4-o)] (L = [PhC(NC6H4iPr2-2,6)2]−, Ln Y (1a), Lu (1b)) with phenylacetylene, CO2, diisopropyl carbodiimide, isocyanide, or PhSSPh lead to the formation a series phosphorus-containing products. The reaction 1 CS2 yields two novel P-methyl-phosphindole-2,3-dithiolate dianion complexes, revealing an unusual tandem desulfurization/coupling/cyclization mode CS2. A...
In this paper, three [Formula: see text],[Formula: text]-conjugated cationic porphyrin compounds were designed and synthesized. The structure of the intermediates desired porphyrins confirmed by UV, IR, 1 H NMR, MS elemental analysis. interaction modes between these ct-DNA studied UV-vis spectroscopy fluorescence emission spectroscopy. results showed that PCP had an external binding mode with DNA at low concentration could intercalate increase concentration. 2 interacted through mode, 3...
Rare examples of molecular, dinuclear CeIII and PrIII complexes with robust Ln-coordination are accessible by use the tetraphenolate pTP as a supporting, chelating O-donor ligand platform, = [{2-(OC6H2R2-2,4)2CH}-C6H4-1,4]4- that favours higher formal oxidation states to rare earths. Two classes have been made from platforms; one metallacyclic 2 + [Ln2(pTP)2] framework rigid, letterbox-shaped geometry [Ln(aryloxide)4] core, more flexible [(LnX)2(pTP)] earth ion at either end platform. The...

β-ketoimidazol(in)ium salts show contrasting reactivity with MHBEt<sub>3</sub>due to subtle electronic and steric differences. Thermolysis of the chiral β-borate imidazolium formed from these reactions results in alkane elimination first example organic borates functioning as Brønsted bases.
Three porphyrin compounds, monomer Por I, dimer II and trimer III have been synthesized from the reaction of cyanuric chloride, 5-(4-hydroxyphenyl)-10,15,20-triphenyl 1-phenylpiperazine.
