Description
A találmány tárgya eljárás új biszfoszfin-számazékok előállítására, amelyek olefinek és szén-monoxid kopolimerizálási eljárásában alkalmazott katalizátorkészítmény komponenseként használhatók.
A találmány szerinti eljárás közelebbről az RP(Ri)2]z (I) általános képletú vegyületek - a képletben
R jelentése alkilén összekötő csoport, amely a hídban 3 szénatomot tartalmaz, és
Rt jelentése fenilcsoport, amely legalább egy 1-4 szénatomos alkoxicsoport-szubsztituenst tartalmaz a foszforatomhoz képest ortohelyzetben előállítására vonatkozik.
A fenti (I) általános képletú vegyületek a HU 202
772 lajstromszámú magyar szabadalmi leírásban ismertetett katalizátorkészítmények komponenseként használhatók olefinek és szén-monoxid kopolimerizálására.
Előnyösek azok az (I) általános képletű vegyületek, amelyek képletében az Rí jelentésére megadott fenilcsoport 1-4 szénatomos alkoxicsoport-szubsztituense metilcsoportot jelent. A fenilcsoport a foszforatomhoz képest ortohelyzetben lévő 1-4 szénatomos alkoxicsoporton kívül további 1-4 szénatomos alkoxicsoportszubsztituenseket is tartalmazhat, amelyek az ortohelyzetben lévő szubsztituenssel azonosak, vagy attól eltérőek lehetnek.
A katalizátorkészítmények komponenseként igen előnyösek az alábbi (I) általános képletű biszfoszfínok:
1.3- bisz[di(2-metoxi-fenil)-foszfíno]-propán,
1.3- bisz[di(2,4-dimetoxi-fenil)-foszfíno]-propán,
1.3- bisz[di(2,6-dimetoxi-fenil)-foszfíno]-propánés
1.3- bisz[di(2,4,6-trimetoxi-fenil)-foszfino]-propán.
Az R[P(Ri)2]a általános képletű foszfinok előállítása egy R(PX2)tt általános képletű dihalogén- foszfin és egy í RíMgY általános képletű megnézrum-halogenid reagáltatásával - a képletekben
R jelentése kétértékű alkiléncsoport,
Rí jelentése finilcsoport, amely legalább egy 1-4 szénatomos alkoxicsoport-szubsztituenst tartalmaz a i foszforatomhoz képest ortohelyzetben,
X és Y jelentése azonos vagy eltérő halogénatom, és n értéke 2 a szakirodalomból ismert (Houben-Weyl, „Methoden dér otganischen Chemie, 12/1 kötet, 34-38. oldal, 1963). z Az (I) általános képletű új vegyületeket a diaril-alkil-foszfinok előállítására alkalmas eljárásokkal állíthatjuk elő, például úgy, hogy egy bisz(dihalogén-foszfíno)-alkánt egy arü-magnézium-halogeniddel reagáltatunk, a Grignard-reakció feltételei között. 5
Szakember számára nyilvánvaló, hogy a Grignardreakciót oxigén, víz és szén-dioxid kizárásával kell végrehajtani. A Grignard-reakciőt általában éteroldőszerben játszatjuk le, például dietil-éterben vagy tetrahidrofuránban. Az aril-megnézium-halogenidet (Grig- 5 nard-vegyületet) rendszerint frissen állítjuk elő, magnézium-forgácsból és a megfelelő magnézium-halogenidből, éteroldószerben, a Grignard-reagens képződését elősegíthetjük kis mennyiségű dibrom- vagy dijődalkán hozzáadásával. 6l
A találmány szerinti eljárás kiindulási vegyületeként használt bisz(dihalogén-foszfino)-alkánokat például az alábbi reakcióvázlat szerinti eljárással állíthatjuk elő:
R(Hai)2 -4 RffO(OC2H5)2]2 -> R(PH2)2 -> R(PX2)2 5 A fenti eljárás szerint dihalogén-alkánt trietil-foszfinnal reagáltatunk, a kapott alkilén-bisz(dietil-foszfonát)-ot difenü-ón-hidriddel redukáljuk, és az így kapott difoszfino-alkánt egy COX2 általános képletű vegyülettel - például foszgénnel - reagáltatva bisz(dihalo10 gén-foszfino)-alkánná alakítjuk.
A találmány szerinti eljárást közelebbről az alábbi példákkal kívánjuk - a korlátozás szándéka nélkül ismertetni.
1. példa
A reakciókat és a termék izolálását nitrogénatmoszférában hajtjuk végre. A dietil-étert nitrogénatmoszférában, Iítium-alummium-hidridről desztillálva szántjuk. Az összes többi reaktánst használat előtt gázmen) tesítjük.
4,7 g (0,193 mól) magnézium-forgácshoz lassan, keverés közben, szobahőmérsékleten hozzáadjuk 30,71 g (0,164 mól) 2-brőm-anizol 250 ml dietil-éterrel készült oldatát. A Grignard-reagens képződésének iniciálására 2 i csepp 1,2-dibróm-etánt adunk az elegyhez, és enyhén melegítjük. A beadagolás befejezése után a reakcióelegyet 1 órán keresztül visszafolyató hűtő alatt forraljuk. A Grignard-reagens-oldatot szúrjuk és keverés közben, cseppenként hozzáadjuk 6,10 g (24,8 mmól) 1,3bisz(diklőr-foszfino)-propán 300 ml dietil-éteirel készük, -30 - -20 °C-ra hűtött oldatához, A reakcióelegyet ezután 25 ’C-ra melegítjük, és ezen a hőmérsékleten 16 órán keresztül keveq'ük. A reakcióelegyet ezután további két órán keresztül visszafolyató hűtő alatt forraljuk, majd szobahőmérsékletre hűtjük. Jeges fürdőn való hűtés közben a reakcióelegyhez cseppenként 300 ml telített, vizes ammónium-klorid-oldatot adunk. Akapott elegyet 2 órán keresztül keveq'ük. A dietil-éter egy részét desztillálással eltávolítjuk. A maradékhoz 200 ml vizet adunk és a kapott szuszpenziót három részre osztott 700 ml kloroformmal extraháljuk. Az egyesített kloroformos oldatokat ezután desztilláljuk, és a kloroform nyomait vákuumban eltávolítjuk. A kapott viszkózus olajat etanolból kristályosítjuk.
5,93 g (11,1 mól, 45%) l,3-bisz[di(2-metoxi-fenil)foszfíno]-propánt kapunk, olvadáspontja etanolból végzett átkristályosítás után: 151-152 ’C.
31P-NMR-spektrumában (deutero-klorofonnban) a kémiai eltolódás -37,9 ppm. Tömegspektrometriás analízise a várt törzsiont és fragmentumokat mutatja.
2. példa
Az 1. példában leírtak szerint járunk el, azzal az eltéréssel, hogy 2-bróm-anizol helyett l-bróm-2,4-dimetoxi-benzolt használunk.
