In efforts to increase the electrophilicity of the Ti center, 7r-accepting boryl-amide chelates were employed to prepare the complexes TiCl2(((R2B)NCH2)2) (R = C6H2Me3, Cy) and related alkyl... 

EDTD-monoalkylamide chelates were studied by Takeshita et al. [79] and the cmc values of several Ci2-amide chelates are shown in Table 1. Cig-Amide chelate showed high dispersing ability toward TiC>2, and the nickel chelate was the best among them. These chelates exhibited excellent kerosene-emulsilying... 

Baia et synthesised and characterised of a new class of DTPA bis(amide) linked glycoconjugates of different sugars (lactose and galactose) and valencies (di and tetra) and their Ln(III) complexes. The dynamic effects of racemisation of the central nitrogen atom in the NMR spectra show that this process is fast at 60°C for the Sm-III complexes and slow at 7°C for the Eu-III complexes. The water exchange rate and the electron spin relaxation parameters of the Gd-III-DTPALaC(2) complex are within the usual range for similar Gd-III-DTPA bis(amide) chelates.
