- The Photolysis of Octaisopropylcyclotetrasilane; Evidence for the Formation of Hexaisopropylcyclotrisilane and Tetraisopropyldisilene
-
Irradiation of octaisopropylcyclotetrasilane (1) in a hydrocarbon solvent successively afforded hexaisopropylcyclotrisilane i2Si>3 (2) (λmax 320 nm) and tetraisopropyldisilene i2Si=SiPri2> (3) (λmax 400 nm) with extrusion of di-isopropylsilanediyl (4).

- Photolysis of 2,3:5,6-Dibenzo-7,7,8,8-tetraisopropyl-7,8-disilabicycloocta-2,5-diene: Evidence for Cyclodimerization of a Disilene
-
Evidence for disilene dimerization was obtained by generating tetraisopropyldisilene from the title compound via the photochemical retrodiene process which produced the expected dimerization product, octaisopropylcyclotetrasilane (30percent), in addition to the H-abstraction product, 1,1,2,2-tetraisopropyldisilane (5percent).
