REACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES
The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl methacrylate, dimethylacetylene dicarboxylate and N-phenylmaleimide. The reactivity of the former nitrone is found to be minimal. It undergoes, how...
متن کاملEnergetics and Mechanisms for Reactions Involving Nitrosamide, Hydroxydiazenes, and Diimide N-Oxides
Using ab initio techniques, we have solved for the geometries and energies of nine isomers of N,H20 including hydroxy-1,land hydroxy-1 ,2-diazenes1 (e.g., HN=NOH), nitrosamide (H2N-NO), and diimide N-oxides (HN=N(-O)H). The heats of formation obtained from these calculations are used to examine several chemical processes including (i) the reaction H2N + NO N2 + H20, postulated to be a key step ...
متن کاملSyntheses and characterisation of N,N'-biscarbazolyl azine and N,N'-carbazolyl hydrazine derivatives and their antimicrobial studies.
Reaction of 1-oxo-1,2,3,4-tetrahydrocarbazoles 1a-e with hydrazine hydrate in absolute ethanol afforded N,N'-bis-carbazolylazine derivatives 2a-e. Treatment of compounds 1a-e with hydroxylamine hydrochloride in ethanol with a catalytic amount of pyridine resulted in the formation of 1-hydroxyimino-1,2,3,4-tetrahydrocarbazoles 3a-e. Reduction of 3 with hydrazine hydrate in the presence of pallad...

متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
