A focus on phosphinophosphination of apolar bonds by a structurally constrained P-P bonded system.

In this article, we highlight the recent report of Greb on the use of a structurally constrained P-P bonded system for phosphinophosphination of alkenes, alkynes, and carbonyls with high regio- and stereoselectivity (https://doi.org/10.1039/D4SC06581F).

Influence of Pnictogen and Ligand Framework on the Lewis Acidity and Steric Environment in Pnictogen Pincer Complexes.

Pnictogen pincer complexes are a fascinating class of compounds due to their dynamic molecular and electronic structures, and valuable stoichiometric or catalytic reactivity. As recognition of their unique chemistry has grown, so too has the library of pincer ligands employed and pnictogen centres engaged to prepare them. Here we computationally study how the choice of pincer ligand framework and pnictogen influence the electronic and steric outcomes within the complexes obtained.

Why Are Some Pnictogen(III) Pincer Complexes Planar and Others Pyramidal?

Geometrically-constrained pnictogen pincer complexes have emerged in recent years as platforms for unique stoichiometric and catalytic chemical transformations. These complexes feature dynamic conformations ranging from fully planar at the pnictogen centre to distorted-pyramidal geometries, as well as variation between phases. Although the valued reactivity of pnictogen pincer complexes is ascribed to their geometries, there is no unified model to explain the observed conformational outcomes across different ligands and pnictogen centres.

Ligand-enforced geometric constraints and associated reactivity in p-block compounds.

The geometry at an element centre can generally be predicted based on the number of electron pairs around it using valence shell electron pair repulsion (VSEPR) theory. Strategies to distort p-block compounds away from these predicted geometries have gained considerable interest due to the unique structural outcomes, spectroscopic properties or reactivity patterns engendered by such distortion. This review presents an up-to-date group-wise summary of this exciting and rapidly growing field with a focus on understanding how the ligand employed unlocks structural features, which in turn influences the associated reactivity.

Planar bismuth triamides: a tunable platform for main group Lewis acidity and polymerization catalysis.

Geometric deformation in main group compounds can be used to elicit unique properties including strong Lewis acidity. Here we report on a family of bismuth(iii) complexes ( typically pyramidal structure for such compounds), which show a geometric Lewis acidity that can be further tuned by varying the steric and electronic features of the triamide ligand employed. The structural dynamism of the planar bismuth complexes was probed in both the solid and solution phase, revealing at least three distinct modes of intermolecular association.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans.

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans.

Evidence-based posttraumatic stress disorder treatment in a community sample: Military-affiliated versus civilian patient outcomes.

Posttraumatic stress disorder (PTSD) is a significant mental health issue among military service members and veterans. Although the U.S.

Evaluating a community-based training program for evidence-based treatments for PTSD using the RE-AIM framework.

Community mental health providers increasingly serve veterans with posttraumatic stress disorder (PTSD). However, recent surveys find that less than 20% of community providers are adequately trained to implement evidence-based treatments (EBTs) for PTSD. Since 2017, the STRONG STAR Training Initiative (SSTI) model has adapted traditional learning collaboratives aimed at increasing availability of EBTs for PTSD in community settings.

Launching a Competency-Based Training Program in Evidence-Based Treatments for PTSD: Supporting Veteran-Serving Mental Health Providers in Texas.

Community mental health providers play an essential role in delivering services to veterans who either have limited access to U.S. Department of Veterans Affairs (VA) facilities or who prefer to seek care outside of the VA.

Nightmares and Insomnia in the US National Guard: Mental and Physical Health Correlates.

Background: Nightmares and insomnia are significant concerns that commonly co-occur with each other and with other health disorders. Limited research has examined the unique and shared aspects of insomnia and nightmares, and little is known about sleep in US National Guard personnel. This study sought to determine the prevalence and psychosocial correlates of nightmares with and without insomnia in US National Guard personnel.

Bioionic Liquid Conjugation as Universal Approach To Engineer Hemostatic Bioadhesives.

Adhesion to wet and dynamic surfaces is vital for many biomedical applications. However, the development of effective tissue adhesives has been challenged by the required combination of properties, which includes mechanical similarity to the native tissue, high adhesion to wet surfaces, hemostatic properties, biodegradability, high biocompatibility, and ease of use. In this study, we report a novel bioinspired design with bioionic liquid (BIL) conjugated polymers to engineer multifunctional highly sticky, biodegradable, biocompatible, and hemostatic adhesives.
