Thermolysis of 1,1-dimethyl-6-<1,1-dimethyl-2-(trimethylsilyl)ethyl>-4-(pentamethyldisilanyl)silepin in a degassed sealed tube at 250 deg C for 10 h gave 1,1,3,3-tetramethyl-6-(pentamethyldisilanyl)-1-silaindane and 4-(isobutyldimethylsilyl)-1-(pentamethyldisilanyl)-5-(trimethylsilyl)benzene. 3(Isobutyldimethylsilyl)-1-(pentamethyldisilanyl)-4-(trimethylsilyl)benzene was isolated from the mixture after thermolysis of 1,1-dimethyl-6-<1,1-dimethyl-2-(trimethylsilyl)ethyl)>-3-(pentamethyldisilanyl)silepin.
