“… 50 A similar trend was observed in recent studies of the analogous lithium complexes [R-Ar # -Li] 2 (R = t -Bu, SiMe 3 , H, Cl, CF 3 ). 38 We note that the chemical shifts for H-9 are largely unaffected by the identity of the metal ( Table 2 ).…”

“…The reaction between the lithium complexes [R-Ar # -Li] 2 (R-Ar # = 2,6-{2,6-Xyl} 2 -4-R-C 6 H 2 ; R = t -Bu, SiMe 3 , Cl, CF 3 ) 38 with one equivalent of ZnCl 2 , CdCl 2 , or HgBr 2 in a toluene/THF (10:1) mixture at room temperature yielded the Group 12 diaryl species ( t -Bu-Ar # ) 2 M (M = Zn 1 , Cd 2 , Hg 3 ), (Me 3 Si-Ar # ) 2 M (M = Zn 4 , Cd 5 , Hg 6 ), (Cl-Ar # ) 2 M (M = Zn 7 , Cd 8 , Hg 9 ), and (F 3 C-Ar # ) 2 M (M = Zn 10 , Cd 11 , Hg 12 ) according to Scheme 1 . Complexes 1 – 12 were recrystallized from a −30 °C iso -hexane solution to give colorless crystals in low-to-moderate isolated yields.…”
