ESR spectra of l‐cyano‐2‐(trimethylsilyl)ethyl and related radicals were recorded. Temperature dependent ESR spectra of these radicals revealed that electron‐releasing trimethylsilylmethyl and electron‐withdrawing cyano groups synergetically functioned to stabilize the radical centers due to σ‐π captodative effects.
