DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 Li redn. of RCl (R = 7-norbornadienyl) or R2Hg both gave the lithiated norbornadienyl dimer I. 1609-39-8 which is the cas registry number is also used here. I was accompanied by the lithiated LiCl adduct II in the first case, or RLi in the second. The structures were detd. by 1H and 13C NMR, which showed significant J(C7-Li) of 7.6-16.0 Hz. ..
