BIS(4-IMINO-2-PENTANONATO)NlCKEL(n) [Nickel(n) Acetylacetone Imide]... 

This reaction is analogous to the preparation of bis(4-imino-2-pentanonato)copper(II) [bis(4-amino-3-penten-2-onato)copper(II)] described by Holtzclaw, Collman, and Alire, and it consists in mixing an ethanolic solution of the -keto imine ( -imino ketone) with an ammoniacal metal salt solution. Advantages of this technique are the simplicity of preparation and the fact that acetylacetone imide (4-imino-2-pentanone) can be purchased. The product is useful as a starting material in ligand-exchange reactions. 

Anhydro-4-hydroxyoxazolium hydroxides were first obtained in 1974 by the decomposition of the a-diazoimides (295) induced by copper(II) acetylacetonate. The reaction proceeds by way of a carbene or a carbenoid species (equation 147). The triphenyl derivative is formed when the imide shown in equation (148) is treated with triethyl phosphite (82JOC723). 

Acetoacetic esters, acetylacetone, or malonic acid esters react with cartxxli-imides to give amidines. 

Bi s (2,4-pentanedionato) oxovanadium (I V) [vanadium-(IV) oxy(acetylacetonate)] has been prepared by direct reaction of 2,4-pentanedione and vanadium(V) oxide. By using the same method, bis(4-imino-2-pentanonato)oxo-vanadium(IV) has been prepared by substituting acetyl-acetone imide (4-imino-2-pentanone) for acetylacetone. ... 

Catalyzed peroxide oxidation.1 Amides and lactams are selectively oxidized to imides by f-butyl hydroperoxide or peracetic acid catalyzed by trace amounts of transition metal ions, such as manganic acetylacetonate. For example, 2-piperidone was oxidized to glutarimide (2) in 72% yield by peracetic acid2 catalyzed by the reagent. 

The structures of typical ligands were shown earlier in Figure 1.9 and will also be shown later in Figures 3.1 and 3.2. Complexes include some metal halides, hydrates, amines, amides and imides, such as Ti(NR2)4 (R is an alkyl group), oxides, H3B NR3 (a borane-amine adduct), Co(MNT)2 (MNT = maleonitrile dithiolate), Cupc (pc = phthalocyanine), Mo(CO)6, cluster carbonyls, and metal acetylacetonate derivatives.
