The Synthesis of Unsubstituted Cyclic Imides Using Hydroxylamine under Microwave Irradiation

open access: yesMolecules, 2008
Unsubstituted cyclic imides were synthesized from a series of cyclic anhydrides,hydroxylamine hydrochloride (NH2OH·HCl), and 4-N,N-dimethylamino-pyridine (DMAP,base catalyst) under microwave irradiation in monomode and multimode microwaves.

Synthesis and Characterization of Three-Coordinate Ni(III)-Imide Complexes [PDF]

open access: yes, 2011
A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types ...

Heterogeneous Catalytic Oxidation of Amides to Imides by Manganese Oxides

open access: yesScientific Reports, 2018
Herein, we report a one-step peroxide mediated heterogeneous catalytic oxidation of amides to imides utilizing a series of manganese oxides. Among them, Cs/Mn2O3 was found to be the most active catalyst for the selective partial oxidation of N ...

Fully Chlorinated N-Silyl Amides of Titanium and Tungsten [PDF]

open access: yes, 1997
The reaction of hexachlorodisilazanyllithium (Cl3Si)2NLi (1), with TiCl4 leads selectively to the novel fully chlorinated amides (Cl3Si)2NTiCl3 (2) or [(Cl3Si)2N]2 TiCl2 (3), respectively, depending on the molar ratio of the starting materials.

1-INDANONE DERIVATIVES: A NOVEL ONE-POT APPROACH TO IMIDES VIA BECKMANN-LIKE REARRANGEMENT AND THEORETICAL INSIGHTS INTO THEIR INTERACTIONS WITH ACHE ENZYME [PDF]

open access: yesQuímica Nova
The reaction of (E)-2,3-dihydro-1H-inden-1-one oxime (3) with carboxylic acid anhydrides and fatty acids aiming at the formation of the respective esters unexpectedly produced imides [5a-5c and 5d-5k] (81-95% yields).
