反応手順
The preparation of 3-hydroxy-3-phenylbutan-2-one by reaction of 2,3-butanedione with an appropriate Grignard reagent is described in an article by Lapkin and Golovkova in Zuhr. Obshchei Khim (J. Gen. Chem.) 19, 701-6 (1949) and abstracted in Chemical Abstracts 44, 1057h (1950). The reaction of biacetyl with phenylmagnesium bromide (31.4 g) gave 30% methylphenylacetylcarbinol. The reaction conditions are not specifically described but earlier in the abstract the solvent used was diethyl ether and the reactants were heated for 10 hours. The preparation is also referred to in Beilsteins Handbook (1969) at page 458.
