Organic synthesis plays a vital role in modern chemistry, which enables one to construct molecules with specific physical and chemical properties for applications in medicinal chemistry, chemical biology and material science. Recently, the development of environmentally friendly and sustainable conditions applied for organic synthesis is highly desired. Particularly, organic electrosynthesis gains a great amount of attention as alternative strategy. Here, we start with the fundamental setup for electrolysis used for organic synthesis, the application of direct/mediated/ cation-pool electrolysis to the variants of paired electrolysis. Finally, the combination of electrosynthesis and conventional metal catalyzed cross-coupling reaction to overcome the challenging cross-coupling reactions will be presented. The aim of this article is to serve as a practical beginner's guide for an interesting reader to enter this exciting field.
