20.500.12556/RUL-109550 Spremljanje reakcije bakrovega(II) kinaldinata s piperidinom Monitoring the reaction of copper(II) quinaldinata with piperidine Spremljala sem ponovljivost reakcij [Cu(kinal)2(MeOH)]·MeOH s piperidinom v različnih reakcijskih sistemih. Produkte sem poskušala identificirati z IR-spektroskopijo in praškovno difrakcijo. Pri nižji temperaturi sta izkristalizirala dva produkta, [Cu(kinal)2(Pipe)2] in [Cu(kinal)2(Pipe)2]·2MeCN. Reakcijska zmes, ki vsebuje acetonitril, na sobni temperaturi spremeni barvo, iz modrozelene v rjavordečo. Barvno spremembo opazimo tudi v sistemu s propionitrilom, v sistemu z benzonitrilom se barva v istem reakcijskem času ne spremeni. Ta barvna sprememba najverjetneje pomeni redukcijo bakra(II) ter tudi to, da v reakcijski zmesi ne poteka le enostavna substitucija metanola s piperidinom, temveč tudi druge, bolj zapletene reakcije. Reactions of [Cu(kinal)2(MeOH)]·MeOH with piperidine in different reaction systems were monitored. The products were identified by means of infrared spectroscopy and X-ray powder diffraction. At 4 °C, two products crystallized. Their compositions were [Cu(kinal)2(Pipe)2] and [Cu(kinal)2(Pipe)2]·2MeCN. The reaction mixture containing acetonitrile changes colour at ambient conditions. Its colour changed from blue-green to brown-red. Similar colour change was detected in a system with propionitrile, whereas a system with benzonitrile in the same reaction time retained the initial colour. This colour change most likely suggests reduction of copper(II) and that apart from a substitution of methanol with piperidine other, more complicated reactions are taking place in the reaction mixture.
