Abstract:

Click chemistry has been widely developed and applied to various fields such as polymers, chemical synthesis, and biology. In recent years, thiol-ene reaction as a type of click chemistry has attracted much attention because it is highly efficient and can be photo-initiated without using toxic metal catalysts. In this paper, the method of photo-initiated disulfide-ene chemistry is introduced. To avoid short-comings of thiol-ene chemistry such as ease of oxidation of thiols and various side reactions, photo-ininitated reactions between disulfides and enes as potential and alternative reactions were studied. Experimental data showed that the reaction rate and yield were affected by various reaction conditions such as oxygen, photo-initiators, different reactants and solvents.

Key words: disulfide, ene, click chemistry, photo-initiation
