✦ Synopsis
o-hydroxyghenyl benzyl ketones on treatment with dimethyl sulphoxide and powdered potassium hydroxide have been found to unciergo facile oxidation to the corresponding benzils. In a recent paper' from these laboratolies o-hydroxyphenyl benzyl ketones derived from resorcinol and phloro!glucinol units on reaction with dichloroacetic acid in aqueous alkaline medium were found to give the cornsponding phenyi(OC-carboxyvinyl)benzyl ketones and 2-carboxymethyl-2-phenyl-126-7 2393 55 86-7 862 65 99-100 *** 80 135 *c* 75 127-8 *rM 80 109-10 *** 65 146-8 a** 80 154 +**
