A fluorescent, strongly Lewis-acidic borenium cation (Gutmann–Beckett acceptor number >100) was created using a tridentate formazanate ligand. This cation shows a potential utility as a colourimetric reactivity probe.

The purpose of this article is to provide a sociological typology for understanding the different types of practitioners within the Tibetan Buddhist organization, Rokpa International, in Scotland. It will be argued that the empirically derived criteria and Weber’s (1978) sociological concepts of authority, power and status allow us to understand the tensions and mutually dependent relationship between the different types. In conclusion, it will be argued that, while this typology is not presented as a challenge to existing typologies, this article demonstrates the potential utility of these sociological concepts for understanding the practice and development of Buddhism in the West.

Herein we report the 3,5bistrifluoromethylphenyl urea-catalyzed functionalization of unactivated C–H bonds. In this system, the urea catalyst mediates the formation of high-energy vinyl carbocations that undergo facile C–H insertion and Friedel–Crafts reactions. We introduce a new paradigm for these privileged scaffolds where the combination of hydrogen bonding motifs and strong bases affords highly active Lewis acid catalysts capable of ionizing strong C–O bonds. Despite the highly Lewis acidic nature of these catalysts that enables triflate abstraction from sp<sup>2</sup> carbons, these newly found reaction conditions allow for the formation of heterocycles and tolerate highly Lewis basic heteroaromatic substrates. This strategy showcases the potential utility of dicoordinated vinyl carbocations in organic synthesis.<br>

Abstract ‘Flipped learning’ has become increasingly popular in medical education as a means of developing independent learning skills in students. The article by Zheng at al. (2020) highlights the potential utility of this approach in disaster triage training. However, the article also highlights to us some concerns regarding how ‘flipped learning’ may favour certain learners over others in the provision of disaster triage education. Specifically, the article demonstrates the necessity for increased pre-classroom preparation when a ‘flipped classroom’ model is employed which inevitably privileges those with a higher ability to engage with self-directed learning. Whilst such a skill is important to develop in medical education, we fear it may lead to polarised student attainment rather than ensuring a maximum number of students achieve the requisite standard required. More research is consequently needed to inform the most efficacious means of facilitating disaster triage training that supports all students sufficiently whilst also helping to nurture their independent learning skills.
