The aptitude of a frustrated Lewis pairs to capture NO nitric oxide to produce aminoxyl radicals is a recent triumph of FLP chemistry, where Mes is 1,3,5-trimethylphenyl.
Identify the frustrated Lewis pair and define why it is frustrated. Utilize a molecular orbital argument to rationalize why the N-O bond lengthens in the complex relative to free nitric oxide.
