- PREPARATION AND ALKYLATION REACTIONS OF 4-NITROBENZYL AND 5-NITROFURFURYL SULFONES
-
Substitution reaction of 5-nitrofurfuryl bromide (I) with sodium thiophenoxide and 4-chlorothiophenoxide in dimethyl sulfoxide at 20 deg C and oxidation with dimethyl sulfoxide in the reaction medium afforded 5-nitrofurfuryl phenyl sulfone (IVa) and 5-nit

- Radical-Nucleophilic Substitution (SRN1) Reactions: Electron Spin Resonance Studies of Electron-capture Processes. Part 4.1 α-Substituted 2-Methyl-5-nitrofurans
-
We have probed two steps postulated for the radical-nucleophilic substitution (SRN1) mechanism for α-substituted 2-methyl-5-nitrofurans (O2NFurCH2X) by detecting the intermediates involved using e.s.r. spectroscopy.These two steps are the elect

- ELECTRON TRANSFER PROCESSES. REACTION OF 5-NITROFURYL DERIVATIVES GOING BY ANIONRADICAL MECHANISM
-
5-nitrofurfuryl nitrate and bromide (1a,b) react with electron donors to give 1,2-bis(5-nitro-2-furyl)ethane (II), 1,2-bis(5-nitro-2-furyl)ethylene (III), 5-nitro-2-methylfurane (IV), products of SRN1 reactions Va, Vb and other derivatives.Formation of the derivatives II to V is discussed on the basis of anionradical mechanism. 5-Nitrobenzyl bromide reacts by a SRN1 reaction with 5-nitrofurfuryl phenyl sulphone (Va) in basic medium to give 1-(5-nitro-2-furyl)-1-phenylsulphonyl-2-(4-nitrophenyl)ethane (VIII) and 1-(5-nitro-2-furyl)-2-(4-nitrophenyl)ethylene (IX).
