Alcohol (drug)

Alcohol, sometimes referred to by the chemical name ethanol, is a depressant drug that is the active ingredient in drinks such as beer, wine, and distilled spirits (hard liquor). It is one of the oldest and most commonly consumed recreational drugs, causing the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces happiness and euphoria, decreased anxiety, increased sociability, sedation, impairment of cognitive, memory, motor, and sensory function, and generalized depression of central nervous system (CNS) function. Ethanol is only one of several types of alcohol, but it is the only type of alcohol that is found in alcoholic beverages or commonly used for recreational purposes; other alcohols such as methanol and isopropyl alcohol are significantly more toxic. A mild, brief exposure to isopropanol, being only moderately more toxic than ethanol, is unlikely to cause any serious harm. Methanol, being prof

Remote C(sp 3 )−H Arylation and Vinylation of N ‐Alkoxypyridinium Salts to δ‐Aryl and δ‐Vinyl Alcohols

Xu Bao, Qian Wang, Jieping Zhu

The reaction of readily available and benchstable N-alkoxypyridinium salts with arylboronic and vinylboronic acids afforded d-aryl and d-vinyl alcohols, respectively, in the presence of fac-Ir(ppy)3 and Cu(OTf)2 dual catalysts. The reaction takes place through a domino process involving the reductive generation of alkoxyl radicals, 1,5-hydrogen atom transfer (1,5-HAT) and the copper-catalyzed cross-coupling reaction of the resulting translocated carbon radicals with boronic acids. Complementary to the Minisci reaction, this method allows for the arylation of nucleophilic alkyl radicals with both electron-rich and electron-poor arenes under mild reaction conditions.

Youth nightlife at home: towards a feminist conceptualisation of home

Daniel Gatica-Perez, Darshan Santani

This paper explores home as a space of youth nightlife and drinking through a feminist lens. It draws on feminist geographical scholarship on home and 40 semi-structured interviews with young people aged 16–25 in Switzerland in the context of a larger interdisciplinary study. We find that the home figures as a central space of nightlife for young people beyond pre-drinking or home parties. At the same time, privacy and intimacy are important to young people when drinking alcohol outside of the home. We suggest that this preference of privacy when going out indicates an interweaving of private and public spheres in young people’s nightlives. The paper argues that the home is both a central concrete space and an important symbolic notion in young people’s nightlives. In so doing, it empirically complicates the public/private dualism and contributes to feminist geographical conceptualisations of home in the context of youth nightlife.
