NO your pairs : The intramolecular frustrated Lewis pair (FLP) Mes 2 PCH 2 CH 2 B(C 6 F 5 ) 2 captures NO to give the novel N ‐oxyl radical P/B‐FLP‐NO . (see scheme). Coordination of NO to the FLP incites H‐atom abstraction reactivity with cyclohexene and ethylbenzene to give P/B‐FLP‐NOH and the O‐functionalized P/B‐FLP‐NOR species.
