Controllable Z/E-selective synthesis of α-amino-ketoximes from N-nitrososulfonamides and aryl alkenes under neutral conditions

An amidoximation of alkenes with N-nitrososulfonamides enabled by triplet energy transfer under neutral conditions is presented. Both (Z)- and (E)-α-amino-ketoximes are selectively accessible depending on the triplet energy of the photosensitizer.
