Monohydroxylated Ketones

Martin, Aromatic Hydroxyketones Preparation and Physical Properties, [Pg.501]

Also obtained by irradiation of 2-biphenylyl benzoate with 254 nm light in benzene (27%) [1397]. m.p. 195°2-197° [1401]  [Pg.503]

3 Poly phenyl Phenyl Methanones (Class of METHANONES) [Pg.504]

OH - Preparation by heating 3-methyl-5-[(triiso-propylsilyl) oxy]-biphenyl-2-yl phenyl ketone in ethanol with 2 N aqueous hydrochloric acid for 4.5 h at 80° in a sealed tube (93%) [833], [Pg.504]

CO—H Preparation by reaction of n-octyl chloride with 2.4-dihvdroxv-4 - [Pg.507]

Since Hassner s initial report in 1975,7 oxidation of an enol silyl ether with peracid has been a reliable method for the preparation of a-siloxy and ot-hydroxy ketones. However, the submitters have found that, if the enol silyl ether possesses certain structural features, the reaction, with more than two equivalents of the oxidant, affords oc.a -dihydroxylated ketones (i.e., introduction of two oxygen atoms in a single-step) instead of the expected monohydroxylated compounds.8... [Pg.128]
