Photochemical Reductive <i>cis</i>‐Elimination in <i>cis</i>‐Diazidobis(triphenylphosphane)platinum(<scp>II</scp>) Evidence of the Formation of Bis(triphenylphosphane)platinum(0) and Hexaazabenzene

Abstract

Can cyclo-N6 exist? Evidence for the formation of this formal benzene analogue was obtained on irradiation of the complex (1) at 77 K. Unequivocal proof will probably be extremely difficult. The much-discussed intermediate (2) could be characterized for the first time by emission spectroscopy.
