σ-Bond initiated generation of aryl radicals from aryl diazonium salts

σ-Bond nucleophiles and molecular oxygen transform aryl diazonium salts into aryl radicals. Experimental and computational studies show that Hantzsch esters transfer hydride to aryl diazonium species, and that oxygen initiates radical fragmentation of the diazene intermediate to produce aryl radicals. The operational simplicity of this addition-fragmentation process for the generation of aryl radicals, by a polar-radical crossover mechanism, has been illustrated in a variety of bond-forming reactions.

Regioselective transition metal- and halogen-free direct dithiolation at C(sp3)-H of nitrotoluenes with diaryl disulfides

Here we describe a potassium tert-butoxide-mediated regioselective direct C-S bond formation at the C(sp3)-H position of nitrotoluenes with disulfides in DMSO at room temperature. The developed reaction generated, in good yields, various dithioacetals having OMe, halogen, and NH2 functionalities at various positions of the arene rings of the disulfides. Interestingly, in the absence of nitrotoluene, diaryl disulfides and diselenides underwent one-carbon homologation to form dithioacetals and diselenoacetals. Synthesized dithioacetals were transformed into 4-nitrobenzaldehyde and 7-(bis(phenylthio)methyl)-1H-indole.

Reaction of Aryl Aldehydes with Thiocyanates in the Presence of Tributylphosphine

Aryl aldehydes react with methyl thiocyanate in the presence of tributylphosphine to afford S-methyl thiobenzoates and arylacetonitriles in good yields.This is a novel disproportionation reaction involving carbon-carbon bond formation.These compounds thus obtained are easily converted into deoxybenzoins using sodium hydride.On the other hand, p-dialkylaminobenzaldehydes react with methyl thiocyanate under the same conditions to furnish both the corresponding trans-dicyanostilbenes and succinonitriles in moderate yields.Finally, the reaction was carried out with aryl thiocyanates resulting in the formation of addition products.

DEOXYBENZOINS FROM AROMATIC ALDEHYDES

Aromatic aldehydes were easily converted into the corresponding deoxybenzoins by treatment with methyl thiocyanate in the presence of tributylphosphine, followed by addition of sodium hydride.
