Abstract

Abstract Addition of organolithium reagents to p-benzoquinones in ether gives the corresponding 4-alkyl-4-hydroxycyclohexa-2, 5-dien-1-ones. Addition of excess of the reagent to the p-benzoquinones, or to the 4-alkyl-4-hydroxycyclohexa-2, 5-dien-1-ones, in tetrahydrofuran, gives the corresponding dialkylcyclohexa-2, 5-diene-1, 4-diols.
