Oxygen, with alcohols photochemical generation

Although the fundamental breakthrough in the field of silaaromatics resulted from their successful pyrolytic generation as described below, a few photochemical approaches are known as well. Trapping with alcohols, oxygen or acetylenes produced evidence that the photolysis of the precursor 78 yields hexamethyl-l,4-disilabenzene (79) as the initial transient product (equation 147)314.
