Abstract
Darbā ir ietverta vispārīga informācija par jonu šķidrumiem, to uzbūvi, īpašībām, iegūšanu un pielietošanu organiskās ķīmijas reakcijās. Darba gaitā ir sintizēti 1-butil-3-metilimidazolija un N-oktilpiridīnija bromīda jonu šķidrumi. Veikta 1-butil-3-metilimidazolija bromīda jonu šķidruma bromīda anjona apmaiņa uz tetrafluorborāta anjonu. Pētīta piperazīna reakcija ar benzaldehīdu. Veiktas 2-etoksikarbonil-ciklopentanona, indān-1,3-diona un 2-ciānoindān-1,3-diona sintēzes organiskajos šķīdinātājos un 1-butil-3-metilimidazolija tetrafluorborāta jonu šķidrumā. Darba gaitā veiktas arī dimedona reakcijas ar m-nitrobenzaldehīdu etilspirta šķīdumā un 1-butil-3-metilimidazolija un N-oktilpiridīnija bromīda jonu šķidrumos. Noteiktas sintizēto reakcijas produktu kušanas temperatūras un struktūras ir apstiprinātas ar IS, 1H – KMR spektriem.
General information about ionic liquids, their structure, qualities, reception and application in reactions of organic synthesis is collected. In work ionic solutions 1-butyl-3-methilimidazlolium and N-oktyl-piridinium bromide have been synthesized. The anion metathesis reaction with 1-butyl-3-methilimidazlolium bromide to tetrafluoroborate is made. The study of piperazine reaction whith benzaldehyde have been made. Syntheses of 2-ethoxycarbonilcyclopentanone, indan-1,3-dione and 2-cyanoindan-1,3-dione in organic solvents and 1-butyl-3-methil-imidazlolium tetrafluoroborate is made. Also the reaction of dimedone with m-nitrobenzaldehyde in ethyl alcohol and 1-butyl-3-methil-imidazlolium and N-oktyl-piridinium bromide ionic liquids is made. The melting point of reaction products is determined and the IR, 1H – KMR spectra data is achieved.
