Characteristics of ADHD in Struggling Residents and Fellows.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition that often results in poor academic performance. Little is known about how ADHD manifests in residents and fellows. To describe the prevalence and phenotype of ADHD among residents and fellows referred to a centralized remediation program.

A low-coordinate platinum(0)-germylene for E-H bond activation and catalytic hydrodehalogenation.

Pairing transition metals and heavier tetrylenes (Si, Ge, Sn, Pb) holds great potential for cooperative bond activation and catalysis. In this work, we investigate the reactivity of a low-coordinate Pt(0)/Ge(II) system that emerges from the reaction between the monoligated platinum(0) precursor [(PMeAr)Pt(olefin)] with germylene dimer [ArGeCl] (where Ar = CH-2,6-(CH-2,6-Pr)). The resulting complex reveals ability for cooperative bond activation.

Neuropsychological performance labels: do patients understand?

Objective:  Descriptive labels to communicate performance are integral in neuropsychological reports. Although the American Academy of Clinical Neuropsychology (AACN) reached consensus on standardizing uniform labels of performance, consumer understanding of these labels is unclear. This pilot prospective cohort study evaluated patient, family member, and medical provider understanding of neuropsychological performance labels.

Tuning the Inorganic Core of a reduced NiGe Cluster.

Tetranuclear cores (M-E) of transition metals (M) and tetrylenes (E=Si, Ge, Sn) are key motifs in homogeneous and heterogeneous catalysis. They exhibit a continuum of M-M and E-E bonding within the inorganic core that leads to a variety of structures for which there are no specific synthetic methods. Herein, we report a series of highly reduced [NiGe] squares solely stabilized by bulky terphenyl (CH-2,6-Ar) ligands, for which we provide complementary and high-yielding syntheses.

Mechanistic Investigations on Hydrogenation, Isomerization and Hydrosilylation Reactions Mediated by a Germyl-Rhodium System.

We recently disclosed a dehydrogenative double C-H bond activation reaction in the unusual pincer-type rhodium-germyl complex [(Ar)ClGeRh] (Ar=CH-2,6-(CH-2,4,6-Me)). Herein we investigate the catalytic applications of this Rh/Ge system in several transformations, namely semihydrogenation of internal alkynes, -isomerization of olefins and hydrosilylation of alkynes. We have compared the activity and selectivity of this catalyst against other common rhodium precursors, as well as related sterically hindered rhodium complexes, being the one with the germyl fragment superior in terms of selectivity towards -isomers.
