以1,4-二碘丁烷为中间体双螺环螺恶嗪的合成与表征

The synthesis of bis-spironaphthoxazine using 1,4-diiodobutane as a medium and the characterization of the product

有关螺恶嗪的衍生物的光致变色研究已有多人报道,主要集中在两个方面:一是设计不同的螺恶嗪分子,研究分子结构对光致变色行为的影响;另一方面是探讨介质对光致变色行为的影响。文中以 1,4 二碘丁烷为中间体,合成了双螺环螺恶嗪。通过 IR,1H NMR手段进行表征,确认了产物结构。

Among the vast number of reports on the photochrometry of spirooxazine derivatives in the literature, researchers are mainly interested in two aspects: one designs different spirooxazines, and looks into the influence of the structure on the photochromic behaviour; the other inquires into the (influence) of the medium on photochromic behaviour. In this work, 1,4-diiodobutane was used as the medium to synthesize bis-spirnaphthoxazine. The product was identified by elemental analysis, IR and ~1H NMR, and the resultant structure was confirmed.
