Reaction of the lithium salts of N,N'-dialkyl-2-amino-4-imino-pent-2-enes, nacnac(R)Li(THF) (R = CH2Ph, Cy, nPr, iBu or S-CH(Me)Ph), with half an equivalent of CrCl2(THF)(x) yielded the homoleptic complexes (nacnac(R))(2)Cr. All complexes were characterized by X-ray diffraction studies and displayed a highly symmetric, square-planar coordination around the chromium center with strong boat-like distortions of the diketiminate ligands. Reaction of nacnacRLi(THF) (R = CH2Ph, Cy) with one equivalent of CrCl2(THF)(x) afforded the dimeric complexes nacnac(R)Cr(mu-Cl)}(2). (c) 2010 Elsevier B.V. All rights reserved.
