环状双(环戊二烯基)钛、双(甲基环戊二烯基)钛芳氧基衍生物的合成

SYNTHESIS OF CYCLIC BIS(CYCLOPENTADIENYL) TITANIUM AND BIS(METHYLCYCLOPENTADIENYL) TITANIUM AROMATOXIDE DERIVATIVES

在氨基钠存在下,二氯二茂钛或二氯二(甲基环戊二烯基)钛分别与2,2′—二羟基联苯、1,1′—二羟基—2,2′—联萘或间苯二酚等摩尔量反应,得到了四种新的环状有机钛芳氧基衍生物。而间苯二酚与二氯二(甲基环戊二烯基)钛反应,只得到单取代产物。新合成的衍生物都经元素分析、红外、核磁鉴定。

A series of cyclic bis(cyclopentadienyl)titanium and bis(methylcyclopentadienyl)titanium aromatoxide derivatives have been synthesized by the reaction of Cp2TiQ2or (MeCp)2TiCl2 with 2,2' -dihydrobiphenyl, 1,1'-dihydro-2,2'-binaphthyl or resorcinol in 1:1 molar ratio refluxing in benzene and in the presence of sodamide. When resorcin reacted with (MeCp)2TiCl2, the product was mono-substituted instead of six-membered ring compound. The new derivatives have been characterized on the basis of their elemental analysis and spectral(IR and 1H NMR) studies.
