Description
Postup přípravy akrylofenónov dehydrochloráciou β-chlórpropiofenónov je obecný postup ich přípravy, avšak p-cyklopentylakrylfenón nebol doteraz připravený.The process for preparing acryophenones by dehydrochlorination of β-chloropropiophenones is a general process for their preparation, but p-cyclopentylacrylphenone has not yet been prepared.
Spfiaob přípravy novej zlúčeniny je založený na dehydrochlorácii p-cyklopentyl-β-chlór- , propiofenonu alkalickým octanom v alkoholickom prostředí.The preparation of the novel compound is based on dehydrochlorination of p-cyclopentyl-β-chloro-propiophenone with an alkali acetate in an alcoholic medium.
Uvedená zlúčenina sa mfiže použiť ako medziprodukt organických syntéz, alebo na přípravu polymérov so špeciálnymi vlastnosťami.Said compound can be used as an intermediate of organic syntheses or for the preparation of polymers with special properties.
Příklad g p-cyklopentyl- β-chlórpropiofenónu sa rozpustilo v 40 ml etanolu a zahrialo sa skoro do varu. K roztoku sa přidal horúci roztok 11,8 g CH^COONa . 3 HgO v 40 ml etanolu.Example g of β-cyclopentyl-β-chloropropiophenone was dissolved in 40 ml of ethanol and heated to near boiling point. To the solution was added a hot solution of 11.8 g of CH 2 COONa. 3 HgO in 40 ml ethanol.
Zmes sa povarile intenzívně 2 až 3 minúty a nechala ochladiť. Po ochladení nebola přítomná východisková látka. Z reakčnej zmesi sa etanol odpařil za vákua. Odparok sa zriedil vodou a extrahoval do éteru. Éterový extrekt sa přepral roztokom kyslého uhličitanu sodného a vo200 896The mixture was boiled vigorously for 2 to 3 minutes and allowed to cool. After cooling, no starting material was present. From the reaction mixture, ethanol was evaporated in vacuo. The residue was diluted with water and extracted into ether. The ether extract was washed with a solution of sodium bicarbonate and 200 896
200 001 dou. Sušil ea e bezvodým síranom sodným. Po vákuovom odpaření éteru odparek sa dělil na krátkom atípei silikagélu 0=4 cm, dížka 5 m s eluentom petroléter : benzén 4 : 1. Po vákuovom zahuštění eluétu aa získalo 7,6 g (64 %) skoro bezfarebnej polymerizovateTnej kvapaliny, ktorej Struktúra bola potvrdená NMB a ifi spektrami. p-eyklopentylakrylofenón bezprostředná po přípravě neobsahoval polymér.200 001 dou. Dried and dried with anhydrous sodium sulfate. After evaporation of the ether in vacuo, the residue was separated on a short silica gel pad of 0 = 4 cm, 5 m in length with the petroleum ether: benzene 4: 1 eluent. NMB and ifi spectra. The β-cyclopentylacrylophenone immediately after preparation did not contain polymer.
