Yang, N. C. published the artcilePhotochemical reactions of ketones in solution, Formula: C5H10O, the publication is Journal of the American Chemical Society (1958), 2913-14, database is CAplus.
The light-induced reactions of simple aliphatic ketones in saturated hydrocarbons were studied. Ketones with no γ-H atom gave the corresponding alc. and the addition product with the hydrocarbon. Ketones with γ-H atoms gave Me2CO, an olefin, and a cyclobutanol derivative These reactions differ markedly from those previously observed in the gas phase. The formation of cyclobutanols offers a route to a group of compounds otherwise difficult to prepare A 1:8 mixture of Me2CO and cyclohexane (I) irradiated in quartz yielded a small amount of CH4 and CO. Fractional distillation and gas chromatography yielded Me2CHOH 53, pinacol 15, MeCOCH2COMe 8, and cyclohexyldimethylcarbinol 12%; cyclohexylcyclohexene and hydrocarbon polymers were also obtained. The recovered I showed slight unsaturation Similarly, irradiation of 2-pentanone in I gave Me2CO, C2H4, and 1-methylcyclobutanol (phenylurethan m.p. 141°). Irradiation of 2-octanone in isoöctane gave equimol. amounts of Me2CO and CH2:CHPr (67%), and 17% 1-methyl-2-propylcyclobutanol b9 67-8°, nD20 1.4420, phenylurethan m. 78deg;. Irradiation of 2-nonanone in isoöctane yielded Me2CO, 1-hexene, and 1-methyl-2-butylcyclobutanol, b0.8 49-50°, nD20 1.4441, phenylurethan m.p. 91°. An intramol, mechanism is formulated for the formation of cyclobutanols.
