✦ Synopsis

Vicinal diester dianions have considerable potential as synthetic intermediates, have recently described the formation and basicities of the dimethyl cyclobutane-l,Z-. dicarboxylate dianion (1) and the dimethyl cyclobut-3-ene-1,2-dicarboxylate dianion.* and we We now report some reactions of dianion 1 and outline a simple synthesis of l,Z-dihydrocyclobuta[blnaphthalene-3,8-dione (9),' a naphthoquinone annelated by a 4-membered ring, for which
