Cmp. Kronenburg et al., Structure and reactivity of cyanocuprates containing the monoanionic C,N-chelating aminoasyl ligand [C6H4CH2NMe2-2](-), POLYHEDRON, 19(5), 2000, pp. 553-555
The 2:1 cyanocuprate [Ar2Cu(CN)Li-2(THF)(4)](infinity) (1, Ar = [C6H4CH2NMe
2-2](-)) is obtained as the only product in the reaction of two equivalents
of ArLi with one equivalent of CuCN in tetrahydrofuran (THF) at - 78 degre
es C. The X-ray crystal structure reveals an ionic polymeric chain consisti
ng of consecutive [Ar2Cu](-) and [(THF)(2)LiCNLi(THF)(2)](+) units. Its com
position in THF solution has been investigated. (C) 2000 Elsevier Science L
