Stilbene compounds of the general formula Ia, Ib or Ic R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.3 R.sup.4 R.sup.5 R.sup.6 (Ia) R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.2 R.sup.4 R.sup.5 R.sup.6 --CH.dbd.CH--Ar.sup.3 R.sup.7 R.sup.8 R.sup.9 (Ib) R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.2 (CH.sub.2).sub.n Ar.sup.3 --CH.dbd.CH--Ar.sup.4 R.sup.4 R.sup.5 R.sup.6 (Ic) where Ar.sup.1 to Ar.sup.4 are identical or different aromatic or quasi-aromatic radicals and n is from 0 to 20 and where either at least one of the radicals R.sup.1 to R.sup.6 or R.sup.9 is hydrocarbon-solubilizing alkyl, alkoxy, dialkylamino or diarylamino of 4 or more carbon atoms in the alkyl moiety or, if formula Ic contains no radicals R.sup.1 to R.sup.6, n is not less than 4, are prepared by metalating a toluene/xylene analog R.sup.1 R.sup.2 R.sup.3 ArCH.sub.3 or H.sub.3 CR.sup.4 R.sup.5 R.sup.6 ArCH.sub.3 with an appropriate aldehyde Ar-CHO or dialdehyde OHC-Ar-CHO to form correspondingly substituted metal mono- or dialcoholates which are hydrolyzed/solvolyzed and dehydrated or pyrolyzed, and are used for preparing bifunctional initiators for anionic polymerization.
Stilbene化合物的一般式Ia、Ib或Ic为R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.3 R.sup.4 R.sup.5 R.sup.6(Ia)、R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.2 R.sup.4 R.sup.5 R.sup.6 --CH.dbd.CH--Ar.sup.3 R.sup.7 R.sup.8 R.sup.9(Ib)、R.sup.1 R.sup.2 R.sup.3 Ar.sup.1 --CH.dbd.CH--Ar.sup.2(CH.sub.2).sub.n Ar.sup.3 --CH.dbd.CH--Ar.sup.4 R.sup.4 R.sup.5 R.sup.6(Ic),其中Ar.sup.1至Ar.sup.4是相同或不同的芳香或准芳香基团,n为0至20,且R.sup.1至R.sup.6或R.sup.9中至少一个是烃溶解烷基、烷氧基、二烷基胺或二芳基胺,其烷基部分含有4个或更多碳原子,或者如果式Ic不含有R.sup.1至R.sup.6基团,则n不小于4,通过用适当的醛Ar-CHO或二醛OHC-Ar-CHO金属化类似于甲苯/二甲苯的R.sup.1 R.sup.2 R.sup.3 ArCH.sub.3或H.sub.3 CR.sup.4 R.sup.5 R.sup.6 ArCH.sub.3来制备相应取代的金属单醇或双醇酸盐,然后水解/溶解和脱水或热解,并用于制备阴离子聚合的双功能引发剂。
