Different Types

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>
