Silicon Compounds with Strong Intramolecular Steric Interactions, 41. - Disilene Additions to the CN Multiple Bonds of Isoquinoline and DicyclohexylcarbodiimideTetra-tert-butyldisilene (4), generated photolytically from hexa-tert-butylcyclotrisilane (3), reacts with isoquinoline in a [2 + 2] 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 dicyclohexycarbodiimide (8), however, yields the 1,2,4-azadisiletanimine derivative 10, presumably formed by rearrangement of an intermediate [2 + 2] 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 plane. The smallest bond angles inside the ring occur at the Si atoms.
