Tetradentate bis(aminophenolate) ligands H2salanX and H2bapenX (where X refers to the para-phenolate substituent = H, Me, F, Cl) react with [FeN(SiMe3)2}2] to form iron(II) complexes, which in the presence of suitable donor ligands L (L = pyridine or THF) can be isolated as the complexes [Fe(salanX)(L)2] and [Fe(bapenX)(L)2]. In the absence of donor ligands, either mononuclear complexes, for example
describes the preparation of a series of new 1,4‐diarylsubstituted‐2‐piperazinones by condensation of substituted N,N′‐bis‐(2‐hydroxyphenyl)‐ethylenediamines with glyoxal and the complete 13CNMR spectral assignment accomplished using APT, HMQC and HMBC techniques. Substituent chemical‐shift effects (SCS) were calculated, which showed different values for the lactam‐ and amine‐substituted aromatic rings
