1-Methyl-1-silatricyclo[3.3.0.0]octa-2,6-diene. A silasemibullvalene
Abstract
Sensitized photolysis of 1-methyl-1-silabicyclo[2.2.2]octatriene (silabarrelene) quantitatively affords the first example of a silasemibullvalene; no evidence for thermally induced Cope rearrangement of the title compound was found.
