In order to examine the reactivities and configurations of imidyl radicals, several cyclic N-bromo imides possessing five- or six-membered imide rings have been photolytically decomposed in the presence of 1,1-dichloroethene in methylene chloride in order to scavenge bromine atoms and bromine.The five-membered N-bromo imides and (+/-)-N-bromocamphorimide undergo ring opening to afford products derived from C-bromo acyl isocyanates.While the corresponding imidyl radicals abstract a hydrogen atom from methylene chloride, none of them undergo intramolecular H-atom abstraction to effect an intramolecular hydrogen-bromine exchange reaction, even when there are suitable located C-H bonds at a fifth (or sixth) position that can overlap the ?-orbital of the imidyl radicals.This phenomenon clearly reveals the presence of stereoelectronic controls on the intramolecular H-abstraction of imidyl radicals, and indicates that the reactive state of imidyl radicals does not possess the Pi-electronic configuration.We conclude that imidyl radicals possess the Sigma-electronic configuration in their reactive state (which is probably the ground state).The intramolecular addition of a C-radical centre to an isocyanate group is established; this indicates that the reversibility of the ring-opening reaction of imidyl radicals is controlled by steric strains among other factors.Because of the presence of reactive allylic hydrogens, the N-bromo imide (10) upon photolysis forms the C-bromo-compounds (11) efficiently by a bromine atom chain process which is retarded by the presence of a better Br<*> scavenging alkene.

An intriguing C?N transformation involving a catalyst-free N-alkylation/N?-arylation process in a multicomponent reaction with secondary amines, cyclic tertiary amines and electron-deficient aryl halides has been described. In this case, the N-alkylation of secondary amines, utilizing cyclic tertiary amines as alkyl group sources, is enabled by a facile C?N cleavage. Such an operationally simple method could facilitate access to aromatic aminoalkyl amines, nitrogen-containing bioactive molecules, in good to excellent yields.

The synthesis and some of the physical properties of the first poly(disulfidediamines) are reported. The disulfidediamine functional group (R2NSSNR2) possesses a disulfide bond in a unique environment that leads to a low bond dissociation energy (calculated BDE of 43.1 kcal mol-1). These polymers were synthesized in high yields and with conversions up to >98% by reactions between secondary diamines and a new disulfide monomer. The disulfide monomer was synthesized in two steps without the need for column chromatography. The polymerizations were robust and completed at room temperature, under ambient atmospheric conditions, and in solvents that were used as purchased. These polymers were stable, but they rapidly decomposed under acidic, aqueous conditions or by heating to 175 C as shown by thermal gravimetric analysis. The first fully conjugated poly(disulfidediamine) was synthesized, and its electrical conductivity was characterized in the solid state.

Efficient microwave assisted syntheses of unsubstituted cyclic imides

A number of cyclic imides were synthesized from cyclic anhydrides using ammonium chloride (NH4Cl), and 4-N,N-dimethylaminopyridine (DMAP) or with ammonium acetate (NH4OAc) under microwave irradiation in both a mono-mode and a conventional microwave. Several substituted succinic anhydrides used as reactants were synthesized efficiently by Diels-Alder reactions of maleic anhydride with 1,3-cyclohexadienes in 63-82% for the mono-mode and 72-92% in the conventional microwave ovens. Cyclic imides were synthesized with yields from 50-98%.
