Abstract
A találmány tárgya eljárás (I) általános képletű aromás halogenidekredukálására (II) általános képletű vegyületekké<$TSize=1;SpAbove=0;SpBelow=0;SpInterLn=133;SpInterPar=0;ULineHt=6;ULineSh=17;DULineHt=6;DULineSh=35;StrikeHt=6;StrikeSh=34;OverscHt=6;OverscSh=103;SupSize=0;SupSh=60;SubSize=0;SubSh=19;AtSize=0;><$TSize=1;SpAbove=0;SpBelow=0;SpInterLn=133;SpInterPar=0;ULineHt=6;ULineSh=17;DULineHt=6;DULineSh=35;StrikeHt=6;StrikeSh=34;OverscHt=6;OverscSh=103;SupSize=0;SupSh=60;SubSize=0;SubSh=19;AtSize=0;> Ar-Xn (I), Ar-Hn (II) - a képletekben Ar aromás csoportot jelent, ami adott esetben egy vagy többszubsztituenst hordozhat, adott esetben kondenzált gyűrűs lehet ésadott esetben egy vagy több oxigén-, kén- és/vagy nitrogénheteroatomottartalmazhat; X fluor-, klór-, bróm- és/vagy jódatomot jelent; és n értéke 1-10 - hibrid típusú redukálószer felhasználásával, oxigénjelenlétében. A találmány értelmében redukálószerként diizobutil-alumíniumhidridet, diizobutil-alumínium-hidrid/ZnCl2-ot, alumínium-izopropilátot, nátrium-bisz(2-metoxi-etoxi)-alumínium-hidridet,kálium-tri(szek-butil)-bór-hidridet, lítium-tri(szek-butil)-bór-hidridet, kálium-trisziamil-bór-hidridet, lítium-trisziamil-bór-hidridet, lítium-tri(terc-butoxi)-alumínium-hidridet, lítium-trietoxi-alumínium-hidridet, 9-bór-biciklo(3,3,1)nonánt, lítium-trietil-bór-hidridet, AlH3.AlCl2H-t vagy két vagy több itt felsorolt redukálószerkombinációját használják, a redukciót oldószerben végzik a nedvességkizárásával, és az oxigént oxigén és inert gáz szárított keverékeformájában fúvatják vagy szívatják át a reakcióelegyen.
