Abstract

Recently, we reported the photolysis of the first peralkyl- cyclotrisilane, [ ( B u ~ CH ~ ) ~ S ~ ] ~ [A,,,, 310 nm(sh)], which af- forded the first peralkyldisilene, (B~fcH~)~Si=si( ... (Amax, 400 nm).l Subsequently we also found that peralkyl- cyclotetrasilanes, [R1R2SiI4, undergo photolysis to give suc- cessively cyclotrisilanes, [R1R2SiI3, and disilenes, R1R2- Si=SiRlR2, with extrusion of silanediyls, :SiR1R2.2 Following our interest in the photochemical behaviour of small- ...
