Description
【技术领域】
本发明属于催化有机合成领域,具体地说涉及一种芳基硫醚类化合物及其制备方法。
【背景技术】
有机硫化合物是一类重要的生物有机化合物,可以在药物、天然产物和农用化学品中找到。芳基硫化物、亚砜和砜分子在现代制药和农用化学科学中具有重要意义。硫利达嗪是一种经典的神经系统药物,用于治疗成人和儿童的精神分裂症。Ametryn 是一种具有选择性吸收和传导作用的三嗪类除草剂。异恶唑草酮是一种含异恶唑的化合物,是一种作为对羟基苯丙酮酸双加氧酶抑制剂的除草剂(HPPD)。考虑到这些化合物的重要性,开发一种制备芳基硫醚的新工艺具有重要意义。过渡金属催化的芳基(伪)卤化物之间的 C-S 键交叉偶联反应硫醇是合成芳基硫化物最经典、最重要的方法。然而,芳基卤化物相对来说毒性较大,且价格昂贵。
为了更加高效环保的合成芳香硫醚,我们发展了一种新型合成芳香硫醚化合物的方法,即以芳基羧酸和硫醇(酚)为原料,通过脱羰偶联合成芳基硫醚化合物,得到的一些新的芳基硫醚化合物,而且此方法无需特殊的设备要求,产率高,对环境无污染,符合国家提出的生态文明建设的理念。目前,国内外还没有关于通过脱羰偶联合成芳基硫醚化合物的公开文献和专利申请。
【发明内容】
本发明的目的在于在催化剂、配体以及添加剂的作用下,芳基羧酸和硫醇(酚)为原料在有机溶剂中反应,反应结束后经过后处理得到相应的芳基硫醚。该方法具有成本较低,产率高,操作简便、无污染等优点,对于实现其工业化生产具有一定的可行性。为达到上述发明目的,本发明提出以下的技术方案:
一种芳基炔烃类化合物及其合成方法,其中芳基硫醚化合物3的结构式如下:
其中所述Ar为1-萘基、2-萘基、独立或未被取代的芳基。R为取代或未取代的苯基、烷基。其中的苯基上的取代基包括甲基,叔丁基、甲氧基、三氟甲基、腈基、苯基;烷基则为2-萘乙基;烯基则为肉桂基。其中化合物3的合成法,其特征在于,在催化剂、配体、酸酐的作用下,芳基羧酸1和硫醇(酚)2为原料在有机溶剂中反应,反应结束后经过后处理得到相应的芳基硫醚3。
上述合成方法中,其中原料芳基羧酸1和硫醇(酚)2的结构式如下:
所述Ar为1-萘基、2-萘基、独立或未被取代的芳基。R为取代或未取代的苯基、烷基。其中的苯基上的取代基包括C2-C4的甲基,C4的叔丁基、甲氧基、三氟甲基、腈基、苯基;烷基则为2-萘乙基;烯基则为肉桂基。
上述合成方法中,催化剂、配体以及添加剂的作用下,芳基羧酸和硫醇(酚)为原料在有机溶剂中反应,反应结束后经过后处理得到相应的芳基硫醚。
本发明所提供的一类芳基炔烃化合物的合成方法开辟了新的低成本“绿色”途径,其优点在于:目标产物产率均较高,反应条件温和,反应操作简便。

附图图1所示是本发明所提供的制备芳基炔烃化合物的路线图。
