โœฆ Synopsis

Photolysis of 'naphtho-o-carborane' under oxygen leads to the quinone, 5,8-diketonaphthocarborane. Photolysis in the presence of hydrogen donors such as acetonitrile or 1,4-cyclohexadiene leads both to the quinone and 5-ketodihydronaphthocarborane. By contrast, photolysis of 'benzocarborane' under similar conditions leads only to a highly stereo-and regiospecific dimerization.
