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.

Diels-Alder reaction affords circumpyrene tetracarboxydiimide with excited state intramolecular charge transfer character [PDF]

open access: yesCommunications Chemistry
Large polycyclic aromatic hydrocarbon (PAH) imides are promising candidates for optoelectronic applications in view of their narrow optical gaps and/or excited state charge transfer character. Diels–Alder (D–A) reactions of PAHs at bay regions can enable

Building lactams by highly selective hydrodeoxygenation of cyclic imides using an alumina-supported AgRe bimetallic nanocatalyst [PDF]

open access: yesNature Communications
The rational design of robust nanocatalysts containing the suitable active sites for building relevant organic compounds, such as lactams, is a desired approximation towards the development of a sustainable fine chemistry field. In that sense, the design
