| Summary: | Заглавие с экрана The on-demand generation of stable organic radicals from the precursors can be considered as an essential challenge for the plethora of applications. In this work, we prepared N-(methyl)benzyl derivatives of 6- oxoverdazyl radicals via atom transfer radical addition with electron-donating and electron withdrawing substituents and studied their homolysis under heat and light. The kinetic of homolysis was measured, and the dissociating rate constant kd, activation energy Ea and frequency factor A were estimated. It was found that electron withdrawing substituted alkylverdazyl demonstrates the fastest homolysis in both types of external stimulus. The obtained result open new perspectives in the controlled generation of verdazyls and their further application in chemical industry and biological science. |
