2,3-Dichloro-5,6-dicyano-1,4-benzoquinone → HCID 11290387, compound

Participants

Reaction Steps

2,3-Dichloro-5,6-dicyanobenzoquinone (1.362 g, 6.0 mmols) was added to a solution of dimethyl 1,4-dipropyl-5,6,7,8-tetrahydronaphthalene-2,3-dicarboxylate (0.665 g, 2.0 mmols) in benzene (20 ml). The mixture was then refluxed for 24 hours. After filtration, the solvent in the mixture was removed in vacuum. By column chromatography (ethyl acetate/hexane, 1/20) using silica gel, 0.464 g of the title compound was obtained as colorless crystals. The GC yield was 87% and the isolation yield was 71%.
