A direct conversion of C(sp(3))-H bonds to C(sp(3))-N bonds has been achieved by utilizing catalytic N-hydroxyphthalimide (NHPI) and stoichiometric dialkyl azodicarboxylate. NHPI functions as a precursor of the electron-deficient phthalimide N-oxyl radical (PINO) to abstract hydrogens, and dialkyl azodicarboxylate acts
