Reaction of 2'-Hydroxychalcone Dibromides with Me2SO

2'-Hydroxychalcone dibromides on treatment with Me2SO gave 2'-hydroxychalcone, 2'-hydroxy-3'- or 2'-hydroxy-5'-bromochalcone, flavone, monobrominated flavone, 6,8-dibromoflavone, 3-bromoflavone, and 3-, 6-, or 8-dibromoflavone.

Bromhydrination of Chalkones in Dimethyl Sulphoxide

A novel method developed for the preparation of α-bromo-β-hydroxychalkones (IIIa-d) involves bromhydrination of the corresponding chalkones (Ia-d) with bromine water in dimethyl sulphoxide at room temperature.
