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 کاملATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کاملSynthesis and anticonvulsant evaluation of some N-substituted phthalimides.
Two series of phthalimides--one possessing an N-phenoxyalkyl moiety substituted at position 3 or 4 of the phenyl ring (1-9) and the other of N-alkenyl or alkinyl phthalimides (10-18)--were synthesized, evaluated for anticonvulsant activity and had their in silico lipophilicity estimated using computer programs. The anticonvulsant activity of phthalimides containing an unsaturated substituent at...
متن کاملSyntheses, Characterization and Solvatochromism Study of Heteroleptic Chelated Copper(II) Complexes Containing N,N- dibezyl Substituted Ethylenediamine and Acetylacetonate Ligands
A series of new heteroleptic chelated copper(II) complexes that encompass N,N-dibezyl substituted derivative of ethylenediamine (X-diamine) and acetylacetonate (acac) were prepared. The IR and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed. The molar conductivity values of the complexes in different solvents reveals a predominance of elec...
متن کاملMicrowave-assisted synthesis of new N₁,N₄-substituted thiosemicarbazones.
We present an efficient procedure for the synthesis of thirty-six N₁,N₄-substituted thiosemicarbazones, including twenty-five ones that are reported for the first time, using a microwave-assisted methodology for the reaction of thiosemicarbazide intermediates with aldehydes in the presence of glacial acetic acid in ethanol and under solvent free conditions. Overall reaction times (20-40 min whe...
