We have investigated the reactions of aromatic carboxylic acids (p-XC6H4COOH, in which X = F, Cl, Br, I, NO2, CH3, H, OCH3) with methyl thiocyanate in trifluoroacetic acid.It was shown that the starting acids are converted to S-methyl benzothioates and the nitrile of the acid .In addition to starting acid, in the reaction mixtures products of the reaction of CF3COOH with methyl thiocyanate were identified. Keywords: methyl thiocyanate, trifluoroacetic acid, S-methyl benzothioates, methyl mercaptan.

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.

Organic thiocyanates react with tributyltin hydride under homolytic conditions to give thiostannanes (Bu3Sn-SR), which are air-stable and high boiling protected forms of the parent thiols.
A NOVEL DISPROPORTIONATION REACTION OF AROMATIC ALDEHYDES INVOLVING C-C BOND FORMATION

, p. 4985 - 4986 (2007/10/02)
The reaction of aromatic aldehydes with methyl thiocyanate in the presence of tributylphosphine afforded both S-methyl thiobenzoates and phenylacetonitriles via a novel disproportionation pathway involving carbon-carbon bond formation.
