An easy procedure for the preparation of 2-substituted hydroquinones, by addition of organolithium or organomagnesium compounds to 1,4-quinone monoketals followed by acid-catalyzed dienone-phenol type rearrangement, is described. Transformation of the propargylated derivatives to benzofurans is also reported.
