摘要：
Tetraarylsuccinonitriles 2a-e were synthesized via oxidative dimerization of diarylacetonitriles 1a-e in basic media. The thermal decomposition of 2 results in two identical cyanodiarylmethyl radicals 3. Both H-1 and C-13 NMR analyses of 1a-e and 2a-e and ESR spectra of 3a-e are presented and discussed. The results of ESR measurements provide a plausible explanation for the different reactivity of cyanodiarylmethyl radicals 3a-e in free radical polymerization.
