NO your pairs: The intramolecular frustrated Lewis pair (FLP) Mes2PCH2CH2B(C6F5)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.
