Bismuth(III) Chloride-Zinc Promoted Selective Reduction of Aromatic Nitro Compounds to Azoxy Compounds

In the presence of bismuth(III)chloride-metalllic zinc aromatic nitro compounds have been found to be selectively reduced inter and intramolecularly to the corresponding N-oxides at ambient temperature in high yields.

The Role of Titanium and Iron Complexes in the Deoxygenation of Aromatic Nitroso-compounds

Deoxygenation of aromatic nitroso-compounds RNO (R = Ph or biphenyl-2-yl) under very mild conditions by titanium(II) and titanium(III) derivatives such as , 2>, (cp = η5-C5H5), and TiCl3 led to the formation of oxo-complexes and the corresponding azo- and azoxy-organic compounds.Carbazole was not formed, suggesting a metal-controlled pathway for evolution of the plausible intermediate nitrene.Similar results have been obtained using N,N'-ethylenebis(salicylideneiminato)iron(II), , which was converted into 2O>.

Deoxygenation and Desulfurization of Organic Compounds via Transition Metal Atom Cocondensation

Reactions resulting from the cocondensation of transition metal atoms with a variety of oxygen- and sulfur-containing organic compounds are surveyed.Alkenes are the major or exclusive volatile products when epoxides are reacted with Ti, V, Cr, Co, and Ni atoms. 2,6-Dimethylpyridine-N-oxide and dimethyl sulfoxide undergo deoxygenation upon cocondensation with chromium, but diisopropyl ether and decyl methyl ether do not.Dibenzyl ether yields bis(η6-dibenzyl ether)chromium(0) with Cr atoms, but dibenzyl sulfide undergoes desulfurization.Cyclohexanone and cycloheptanone afford low yields of reductive coupling and aldol products when cocondensed with Cr, Co, and Ni atoms.Nitro- and nitrosoarenes are deoxygenated to coupled azo and azoxy products with Cr atoms.Carbazole (3) is obtained from 2-nitrosobiphenyl, implicating nitrene or nitrenoid intermediates.Whereas isocyanides are not formed from isocyanates and metal atoms, they are produced when isothiocyanates are cocondensed with Cr and V atoms.
