Quinone and hydroquinone are familier elecronic systems as components for the charge-transfer (CT) complexes. Recent finding of new phase transition for 1,4-benzoquinhydrone has provided a renewed aspect for such systems to obtain interesting solid state properties. Generally, it is important to modify the electronic systems so as to enhance the degree of CT.The extension of a conjugated system is a typical chemical modification for such a purpose. The introduction of substituents with chalcogen atoms or with capto-dative effect is also important. Utilizing biphenoquinone as an exteneded conjugated system of benzoquinone, I synthesized firstly the alkylthio derivatives of biphenoquinones (1) and biphenohydroquinones (2) by the following method.

醌和对苯二酚是常见的电荷转移络合物的组成部分。最近发现的1，4-苯醌新的相变提供了一个新的方面，这类系统，以获得有趣的固态性能。一般来说，为了提高CT的程度，对电子体系进行修饰是很重要的，共轭体系的延伸是实现这一目的的典型化学修饰。引入具有硫族原子或具有俘获效应的取代基也很重要。利用联苯醌作为苯醌的扩展共轭体系，我首先用下述方法合成了联苯醌（1）和联苯醌（2）的烷硫基衍生物。
