  Protecting-Group-Free Access to a Three-Coordinate Nickel(0) Tris-isocyanide

  摘要：

  Details are presented regarding a convenient synthesis of the nickel trisisocyanide complex Ni(CNArDipp2)(3) (Ar-Dipp2 = 2,6-[i-Pr](2)C6H3)(2)C6H3). A previous synthesis of a Ni tris-isocyanide complex relied on a 11(I) coordination-site protection strategy to discourage the formation of a tetrakis-isocyano complex. However, protecting-group-free access to Ni(CNArr(Dipp2))3 is enabled by the encumbering m-terphenyl isocyanide CNArDipp2. Treatment of Ni(COD)2 with CNArDipp2 affords Ni(COD)(CNArDipp2)2, which is readily oxidized to NiI2(CNArDipp2)2 upon addition of I-2. Reduction of NiI2(CNArDipp2)2 with Mg metal gent:rates Ni(CNArDipp2)3 and does not require the addition of a third equivalent of CNArDipp2. Tris-isocyanide Ni(CNArDipp2)3 is active toward Lewis acid bindin)and oxidative addition reactions. Treatment of Ni(CNArDipp2)3 with TlOTf (OTf = [O3SCF3](-)) generates the salt [TINi(CNArDipp2)(3)] OTf, in which the Ni center functions as a Lewis base toward Tl. The Ni center in Ni(CNArDipp2)(3) also oxidativel adds across C-X bonds in a number of alkyl, aryl, and main-group halides and is accompanied by varying degrees of CNArDipp2 ligand loss. Formation of eta(2)-iminoacyl complexes deactivates the Ni center toward additional reactivity.
