摘要:
The reaction between Zn(OAc)(2) center dot 2H(2)O (1) and the 3-iminoisoindolin-1-ones H2N=CNC(=O)(C6RRRR4)-R-1-R-2-R-3 (R-1-R-4 = H 2; R-1, R-4 = H, R-2, R-3 = Cl 3; R-1, R-3, R-4 = H, R-2 = Me 4) in EtCN at 70 degrees C for ca. 12 h affords the novel family of complexes [Zn{H2N=CNC(=O) C6R1R2R3R4}(2)(OAc)(2)] (R-1 - R-4 = H 5; R-1, R-4 = H, R-2, R-3 = Cl 6; R-1, R-3, R-4 = H, R-2 = Me 7) in excellent (90% and 93% for 5 and 6, correspondingly) to good (64% for 7) yields. The isolated compounds were characterized by elemental analyses (C, H, N), IR, NMR and ESI+-MS. X-ray diffraction data for 2 and 5 indicate that both free (2) and ligated (5) 3-iminoisoindolin-1-ones exist in the zwitterionic form. (C) 2009 Elsevier B.V. All rights reserved.
