Lithium reductions of 7‐chloronorbornadiene and of bis (7‐norbornadienyl)mercury both provide (C 7 H 7 ) 2 Li 2 ( 5a ). This product is accompanied by C 7 H 7 Li 2 Cl ( 5c ) in the first case, and by C 7 H 7 Li ( 5b ) in the second. The theoretically anticipated properties of all three organolithiums are apparent in the consistent C s symmetry of their hydrocarbon ligands, their protolytic destruction by 12‐crown‐4, and their significant J (C(7), Li) ( 5a , 7.6; 5b , 16.0; 5c 8.9 Hz).
