The photochemistry of potassium triphenyl(phenylethynyl)borate (1), tetramethylammonium triphenyl(trans-β-styryl)borate (2), and cesium phenyl(2-phenylcyclopropyl)dimethylborate (3) was studied. When irradiated with UV light, these compounds undergo rearrangements to generate potassium 1,1,2,3-tetraphenylboratirene (4), tetramethylammonium trans-1,1,2,3-tetraphenylboratirane (5), and (unisolated) cesium 1,1-dimethyl-2,4-diphenylboratetane (6), respectively. The mechanism of these reactions appears to be similar to the di-π-methane and cyclopropyl-π-methane routes for the analogous hydrocarbons. The effect of borate structure on the efficiency of these reactions was analyzed. Additionally, the chemical and physical properties of the small-ring borates were probed.
