摘要
二氯二茂钛与取代苯甲醛肟钠在二氯甲烷中反应,生成二茂钛单肟衍生物 Cp_2TiCl(ON=CHAr),其中 Ar 为邻硝基苯基、间硝基苯基、对硝基苯基、邻氯苯基、间氯苯基、3,4-二氯苯基、间甲氧基苯基、对甲氧基苯基、2,4-二甲氧基苯基和3,4-亚甲基二氧苯基。所有这些新化合物在干燥空气中稳定,对潮湿空气敏感.经元素分析和红外、核磁氢谱表征,确认了其结构。
The reactions of bis(cyclopentadienyl) ti-
tanium(Ⅳ) chloride(C_5H_5)_2TiCl_2 with sodium
oximide of substituted benzaldehydes in me-
thylene chloride lead to the formation of deri-
vatives of the type CP_2TiCl(ON=CHAr),wherein
Ar is o-C_6H_4NO_2,m-C_6H_4NO_2,p-C_6H_4NO_2,
o-C_6H_4Cl,m-C_6H_4Cl,3,4-C_6H_3Cl_2,m-C_6H_4OCH_3,
p-C_6H_4OCH_3,2,4-C_6H_3(OCH_3)_2,and 3,4-
C_6H_3(-OCH_2O-).These new compounds are
all stable in dry air but sensitive to moisture.
Their structures were identified by elemental
analysis,IR and ~1HNMR spectra.
