Tetra-tert-butyldisilene (4), generated photolytically from hexa-tert-butylcyclotrisilane (3), reacts with isoquinoline in a cycloaddition to give the 1,2,3-azadisiletane derivative 7, whose structure was determined by X-ray crystallography.Photolysis of 3 in the presence of dicyclohexylcarbodiimide (8), however, yields the 1,2,4-azadisiletanimine derivative 10, presumably formed by rearrangement of an intermediate addition product of 4 to one of the CN bonds of 8.The X-ray structure analysis of 10 reveals that the four ring atoms and the exocyclic nitrogen atom lie exactly in a plane.The smallest bond angles inside the ring occur at the Si atoms.
