The reaction of LGeCl [1; L = CH{(CMe)(2,6-(i)Pr(2)C(6)H(3)N)}(2)] with 1,3-di-tert-butylimidazol-2-ylidene results in the formation of the germylene L'Ge [2; L' = CH{(C=CH(2))(CMe)(2,6-(i)Pr(2)C(6)H(3)N)(2)}]. 2 reacts with ammonia under N-H cleavage to give LGeNH(2) (3). This type of reaction can also be used to activate primary amines. 3 is characterized by microanalysis, multinuclear NMR spectroscopy, and X-ray structural analysis. The single-crystal X-ray structural analysis indicates 3 to be a monomer, and the germanium atom shows a trigonal-pyramidal environment with a stereochemically active lone pair.

A series of 2-pyridone[α]-fused BOPHYs - were prepared via a two-step procedure involving the preparation of enamine, followed by an intramolecular heterocyclization reaction. In addition to being fully conjugated with the BOPHY core pyridone fragment, BOPHYs and have a pyridine group connected to the BOPHY core via one- or two -CH- groups. New BOPHYs were characterized by spectroscopy as well as X-ray diffraction.

The functional properties of tetraaryl compounds, M(aryl) (M = transition metal or group 14 element), are dictated not only by their common tetrahedral geometry but also by their central atom. The identity of this atom may serve to modulate the reactivity, electrochemical, magnetic, and optical behavior of the molecular species, or of extended materials built from appropriate tetraaryl building blocks, but this has not yet been systematically evaluated. Toward this goal, here we probe the influence of Os(IV), C, and Si central atoms on the spectroelectrochemical properties of a series of redox-active tetra(ferrocenylaryl) complexes.

Palladium (Pd) catalysts are promising for electrochemical reduction of CO to CO but often can be deactivated by poisoning owing to the strong affinity of *CO on Pd sites. Theoretical investigations reveal that different configurations of *CO endow specific adsorption energies, thereby dictating the final performances. Here, a regulatory strategy toward *CO absorption configurations is proposed to alleviate CO poisoning by simultaneously incorporating Cu and Zn atoms into ultrathin Pd nanosheets (NSs).

Altered neural signaling in fibromyalgia syndrome (FM) was investigated with functional magnetic resonance imaging (fMRI). We employed a novel fMRI network analysis method, Structural and Physiological Modeling (SAPM), which provides more detailed information than previous methods. The study involved brain fMRI data from participants with FM (N = 22) and a control group (HC, N = 18), acquired during a noxious stimulation paradigm.
