A novel bulky aryllithium, 2,6‐bis{2,5‐bis[bis(trimethylsilyl)methyl]phenyl}phenyllithium (BbspLi), was synthesized. Reactions of BbspLi 5 with Group 14 electrophiles, such as stannous chloride, with carbon tetrachloride or tetrachlorometallanes gave fluorene 6 . Reaction of BbspLi with carbon tetrachloride gave benzyl chloride 8 , which converted to 6 under acidic conditions. BbspLi 5 isomerized to the corresponding benzyl anion 10 , which underwent halophilic reactions with Group 14 electrophiles to give fluorene 6 via the benzyl chloride intermediate 8 .
