Bonding and stability of dinitrogen-bonded donor base-stabilized Si(0)/Ge(0) species [(cAAC-Si/Ge)(N)]: EDA-NOCV analysis.

Recently, dinitrogen (N) binding and its activation have been achieved by non-metal compounds like intermediate cAAC-borylene as (cAAC)(B-Dur)(N) [cAAC = cyclic alkyl(amino) carbene; Dur = aryl group, 2,3,5,6-tetramethylphenyl; B-Dur = borylene]. It has attracted a lot of scientific attention from different research areas because of its future prospects as a potent species towards the metal free reduction of N into ammonia (NH) under mild conditions. Two (cAAC)(B-Dur) units, each of which possesses six valence electrons around the B-centre, are shown to accept σ-donations from the N ligand (B ← N).

Recent advances in cascade reactions and their mechanistic insights: a concise strategy to synthesize complex natural products and organic scaffolds.

The beauty of cascade reactions to bestow us with cumbersome organic scaffolds has made them a cutting-edge area of research. Although the planning of cascades may require intuition, their results can be highly impactful. The development of cascades to provide specific targeted molecules of an appropriate structural and stereochemical framework poses a significant challenge but can serve as one of the most impressive tools in organic synthesis.

The cultural education of academic evaluators: lessons from a university-Hmong community partnership.

This article explores some of the lessons a university-based evaluation team learned while attempting to hire, retain, and work with staff members from a local Hmong community. These staff members were hired to assist a federally-funded community collaborative with implementing and evaluating a family strengthening program for Hmong families with adolescents. Over the course of two years, a succession of individuals were hired and resigned from a key staff position.
