Treatment of the bicyclic chloride A with lithium in tetrahydrofuran (THF) gave the monocyclic product B, CoH9Li. In deuterated THF, B exhibited a single proton NMR signal at 6.72 ppm and a single 13C-NMR signal at about 110 ppm. Treatment of B with tetraethylammonium chloride gave a white solid in which N(C2H5)4 replaces Li. Draw a structure for the lithium derivative B. Cl Draw cations and anions in separate sketchers. Separate structures with +signs from the drop-down menu. Treatment of...
