In our laboratory a precursor route to poly(p-phenylenevinylene) derivatives is developed in which unsymmetrically substituted p-xylene derivatives, possessing a benzylic sulfinylalkyl group, are used as monomers. Because of this unsymmetry, we were forced to investigate thoroughly the synthesis of these sulfoxides, as we start from symmetric and readily accessible molecules, namely, bis(halomethyl)-p-xylene
在我们的实验室中,开发了一种制备聚对对苯乙炔衍生物的前体路线,其中使用具有亚苄基亚磺酰基烷基的不对称取代的对二甲苯衍生物作为单体。由于这种不对称性,我们被迫彻底研究这些亚砜的合成,因为我们从对称且易于获得的分子即双(卤代甲基)-对二甲苯衍生物开始。在以前的出版物中,提出了生产这些不对称取代的亚磺酰基单体的极其有效的新途径。本文扩展了这些先前报告的结果。为了检查这种优雅路线的范围和局限性,将该新方法应用于初始工作中未包括的各种衍生物的合成。
