What is Photochemical Generation of Tetramethyldisilene and Photoinduced 1,2-Silyl-migration about?

Described herein is the first clear evidence of the photochemical generation of tetramethyldisilene which can be efficiently trapped by dienes. An intriguing 1,2-photo-induced silyl migration is also reported. Roak and Peddle have demonstrated for the first time the transient existence of reactive tetramethyldisilene, Me2Si=SiMe2, produced by thermolysis of 7,7,8,8-tetramethyl-7,8-disilabicyclo[2.2.2Jocta-2,5-diene derivatives. 2 In a recent publication, 3 we have proved the geometrical isomerism of thermally generated cis-and trans-1,2-dimethyl-1,2\_diphenyldisilene which demonstrates clearly the double bond nature of disilene. Dimerization of silylenes to the corresponding disilene has also demonstrated. 4 However, there has been no re-
