Description
Vynález sa týká 2-(4-benzoylfenyl)-2-C4-Í3-chlórpropanoyl)fenyljpropánu.
Popísaná je příprava di-2-(4-acetylfenyl)propánu Friedel-Craftsovou acyláciou 2,2-difenylpropánu (Ε. I. du Pont, GB pat. 753 384, Chem. Abstr. 53, 1 253f, 1958, I. L. Kotlyarevskii, A. S. Zanina, N. M. Gusenkova, Izv. Akad. Nauk ZSSR, Ser. Khim 1967, 900). 2—(4— -benzoylfenyl)-2-C4-(3-chlórpropanoyl)fenyljpropán nie je popísaný v literatúre.
Podstatou vynálezu je 2-(4-benzoylfenyl)-2-E4-(3-chlórpropanoyl)fenyljpropán. Spósob přípravy tejto zlúčeniny spočívá v tom, že na 3-chlórpropanoylohlorid v chloride uhličitom v přítomnosti bezvodého chloridu hlinitého sa pósobí 2-(4-benzoylfenyl)-2-fenylpropánom napřed pri teplote nižšej ako 5 °C a neskoršie pri 20 °C počas 30 minút.
Výhodou uvedeného vynálezu je, že umožňuje připravit jednoducho predmetnú zlúčeninu v 30 %-nom výtažku.
Předmětná látka je medziproduktom pre přípravu monomeru a svetlom degradujúcich polymérov .
Příklad
K suspenzií bezvodého chloridu hlinitého (31,2 g, 0,234 mol) v chloride uhličitom (60 ml) sa pri 0 °C přidá 3-chlórpropanoyl-chlorid (15 ml, 0,16 mol). Po kvapkách sa přidá roztok 2-(4-benzoylfenyl)-2-fenylpropánu (30 g, 0,1 mól) v chloride uhličitom (60 ml) tak, aby teplota nevystúpila nad 5 °C. Po přidaní sa zmes mieša 30 minút pri 20 °C, vyleje opatrné do roztoku kyseliny chlorovodíkovéj (10 ml) vo vodě (400 ml), extrahuje chloroformom a extrakt sa zahustí pri zníženom tlaku. Po chromatografickom delení na silikagéle L 100/400 s eluentom benzén: h-hexán 9:1 a zahuštěni sa získá nažltlá viskózna kvapalina (11,7 g, 30 hmot. %). Elementárna analýza pre C25H23°2C1· (390,91) vypočítané: 76,81 hmot. % uhlík, 5,93 hmot. % vodík, nájdené: 77,30 hmot. % uhlík, 6,17 hmot. % vodík. IR (CC14): 1 690 (C=0), 1 660 (C=O), 1 600 cm1 (C=H, aromatické). UV (CHClj): 260 nm (log£= 4,55), 335 (3,0). 1H NMR (CDC13) : 1,63 (s, 6H, CH3), 3,16 až 3,48 (t, 2K, -CHjCO-), 3,65 až 3,90 (t, 2H, -CH2C1), 7,09 až 7,9 (m, 13H, aromatické).
Vynález má použitie v chemickom priemysle pri príprave polymérov vyznačujúcich sa vysokou degradáciou ultrafialovým svetlom.
