A general method for the N-arylation of sulfamides with aryl bromides is described.The protocol leverages a dual-catalytic system of nickel and a photoexcitable iridium complex and proceeds at room temperature under visible light irradiation. Using these tactics, aryl boronic esters and aryl chlorides can be carried through the reaction untouched. Thereby, this method complements known Buchwald-Hartwig coupling methods for N-arylation of sulfamides.

A general method is described for the coupling of (hetero)­aryl bromides with O-alkyl sulfamate esters. The protocol relies on catalytic amounts of nickel and photoexcitable iridium complexes and proceeds under visible light irradiation at ambient temperature. This technology engages a broad range of simple and complex O-alkyl sulfamate ester substrates under mild conditions. Furthermore, it is possible to avoid undesirable N-alkylation, which was found to plague palladium-based protocols for N-arylation of O-alkyl sulfamate esters. These investigations represent the first use of sulfamate esters as nucleophiles in transition metal-catalyzed C–N coupling processes.

Heel pain at or around the insertion of the Achilles tendon is a common presenting complaint affecting both young, active patients and those who are older and more sedentary. So-called posterior heel pain is often presumed to run a self-limiting course over a few months, resolving with rest, weight loss and stretching exercises. However, a small number of patients suffer with increasingly disabling symptoms that are refractory to this regimen. Posterior heel pain is classically split into insertional and non-insertional types, and in order to select an appropriate management plan the diagnosis must be precise. Further management without a clear understanding of the pathology is potentially detrimental to the patient. This review aims to provide a structured approach to careful clinical and radiological assessment and treatment of this condition.

SYNOPSISThe nature of transformation products of high-temperature reactions of thiophosphoryl disulphides with hydroperoxides in the absence and presence of oxidisable substrates and the role of the disulphide in the overall antioxidant mechanism was investigated using a range of techniques such as oxygen absorption, 31P nuclear magnetic resonance (NMR) , gas-liquid chromatography (GLC ) , and peroxide determination. The major transformation products of the above oxidation reactions were found to be the thio-and thiono-phosphoric acids, in addition to mono and polysulphides. At high molar ratios of peroxide to disulphide (>lo), these oxidation products are the main catalysts for peroxide decomposition, while at lower ratios the disulphide itself was found to play a major role in the antioxidant mechanism.

Recent research has highlighted the shifting media representation of para-athletes some of whom have been increasingly visible as national sporting figures. Their mediation entangles themes of disability, nationalism, gender and technology. In this light, we explore New Zealand print media narrativisation of the nation's most prolific disability athlete, para swimmer Sophie Pascoe. First, we contextualise Pascoe's emergence as a national sporting icon characterised by plaudits and awards. Second, we explore the press narrativisation of Pascoe between 2005 and 2020 which entangled intersecting tropes of disability, athleticism, femininity and ‘kiwi’ nationalism. Pascoe is narrated as a national hero who overcomes both competitors and her disability, which is made ‘hypervisible’. There are contradictions and tensions in this narration. Her gendering reflects a ‘post-feminist’ sensibility; poised between individualistic strength and overcoming, yet simultaneously emotional fragility, dependence and dimunition as a ‘babe’ and ‘princess’. Her celebration contradictorily affirms hierarchies of disability, centring the ‘able-disabled’. The mediation of Pascoe is symptomatic of an ableist rehabilitation supercrip narrative that frames New Zealand sport (and the nation writ large) as progressive and inclusive, yet selectively celebrates an idealised type of disabled athlete.
