Bulky substituents do not always provide for a kinetic stabilization. Otherwise one could not explain the fact that the title compound 2 is stable only below −100°C. 2 can be generated by photochemical cleavage of N 2 from 1 in a Trapp mixture at −110°C and characterized spectroscopically. 2 reacts with methanol to give the adduct 3.
