Paquette (Ed.), Wiley, Chichester, 1995, Vol. 3, p. 1952. (b) lithium cyano(dimethylphenylsilyl)-cuprate Idem, Ibid, Vol. 5, p. 3069. [Pg.135]

Preparative Methods prepared by adding 0.5 equiv of dry copper(I) cyanide to dimethylphenylsilyllithium in THF (eq 1), which in turn is generated from chlorodimethylphenyl-silane and lithium metal. Analogous bis(trimethylsilyl)cyano-cuprates are prepared in a similar manner. [Pg.248]

Preparative Methods the title reagent (1), as well as lithium cyano (trimethylsilyl)cuprate [81802-36-0], can be prepared from the corresponding silyllithium species and 1 equiv copper(I) cyanide in ether or THF at —78 to —5°C the precursor silyllithium (2) is generated by the reaction of chlorodimethylphenylsilane with lithium metal in THF or ether (eq 1).
