Organotellurium Compounds for Controlled Radical Polymerization

Organotellurium-mediated radical polymerization (TERP) is a type of controlled radical polymerizations, also known as reversible deactivation radical polymerization, and was developed by Yamago et al.¹⁾ Ethyl 2-methyl-2-(methyltellanyl)propanoate (1), 2-methyl-2-(methyltellanyl)propanenitrile (2), and [1-(methyltellanyl)ethyl]benzene (3) are useful organotellurium compounds as chain transfer agents (CTAs) for TERP. 1, 2, and 3 effectively control the polymerization of vinyl monomers such as styrenes, acrylates, and methacrylates, even with polar functional groups like amino group and carboxy group. In addition, these CTAs have been applied to the synthesis of block copolymers including amphiphilic polymers,²⁾ and the synthesis of hyperbranched polymers using 1 was also reported.³⁾
