“…This intriguing use of sunlight, along with a report cited in Section 3.4 for modification of linear polymers,158 has the potential for being a very important resource for chemical and materials synthesis. Recent new reports of thiol–Michael addition reactions,313318 several of which take advantage of the powerful phosphine315, 317 and primary amine316 nucleophilic catalysts, involve reactions of RAFT polymers that lead to nanoparticle modification,314 end group functionalization and block/grafted copolymers,313, 315, 307 and the synthesis of three‐arm star polymers 316. The recent implementation of the related photoinitiated thiol–yne free‐radical chain reaction has been shown to exhibit essentially the same outstanding characteristics as its thiol–ene counterpart, with the benefit of adding quantitatively two aliphatic thiols per yne unit,319322 thus providing the click synthesis of a wide range of highly functional multimers, highly refractive optical materials, and water‐soluble end‐functionalized polymers.…”

“…According to Rim and Son [104], Trimer 3 (0.20 g, 0.2 mmol) and K 2 CO 3 (0.53 g, 3.8 mmol) were dissolved in 100 ml acetone under inert conditions. Carefully, acryloyl chloride (0.31 ml, 3.8 mmol) was added and the reaction mixture was refluxed overnight.…”

“…Die Verwendung von Sonnenlicht in letztgenannter Studie ist besonders faszinierend und bietet ein enormes Potenzial für die chemische Synthese und Materialsynthese. Neuere Studien zur Thiol‐Michael‐Addition,313318 die in etlichen Fällen von den hier diskutierten, hoch aktiven Phosphanen315, 317 und primären Aminen316 als nucleophilen Katalysatoren Gebrauch machten, umfassen Reaktionen von RAFT‐Polymeren (reversible addition–fragmentation chain transfer), die zur Modifizierung von Nanopartikeln,314 zur Bildung von Block‐ und Pfropfcopolymeren313, 315, 307 und zur Synthese von Sternpolymeren316 eingesetzt wurden. Die verwandte photoinitiierte Thiol‐In‐Kettenreaktion, die erst kürzlich eingeführt wurde, zeigt die gleichen herausragenden Merkmale wie die Thiol‐En‐Reaktion, mit dem zusätzlichen Attribut, dass zwei aliphatische Thiole pro In‐Einheit addiert werden können,319322 wodurch sich hervorragende Möglichkeiten für eine Klicksynthese funktioneller Multimere, hochbrechender optischer Materialien und wasserlöslicher funktioneller Polymere ergeben.…”
