Although benzenethiolate has not yet been observed in natural waters, this nucleophile was included in the tables in order to extend the range of substrates examined. This inclusion was justified on the basis of the similarity in reactivity between benzenethiolate and n-butanethiolate in their nucleophilic attack on n-butyl bromide (Table VII), as well as that between benzenethiolate and ethanethiolate in their dehydrohalogenation of DDT at 2S°C (Table Vm). 

In order to clarify the mechanism, the reaction of carbon disulphide with mercury bis(n-butanethiolate) was studied. On the basis of results obtained, it was suggested that this reaction involved the formation of a coordination complex, followed by the formation of active species containing the Hg-SC(S) bond. Moreover, the cyclic trithiocarbonate, ethylene trithiocarbonate, found to be present in trace amounts in copolymerisation products, was excluded as a possible intermediate for the copolymer formation, since it did not undergo any polymerisation under the given conditions [249],... 

Methoxy-a-tetralone (137), which on formylation at room temperature followed by treatment with n-butanethiol in presence of p-toluenesulfonic acid gave the compound (138), which was converted with lithium dimethylcopper and acetic anhydride to (139). Subjection of (139) to dehydrogenation, hydrolysis and methylation, respectively, yielded (140) which was converted to tetralone (141) by reduction, hydrolysis and methylation of pyralidine enamine. Alkylation of (141) with 2-... 

Disubstitution product (46%) was the only product obtained in the photostimulated reaction of 70 with pinacolone enolate ion while n-butanethiolate ion led to the monosubstitution product in a relatively low yield (22%) 145. 

In contrast to the behaviour observed with amines, the spectra of t-butanethiol and of n-butanethiol are dominated by the loss of the HS radical formed by the cleavage of the adjacent bond. The ion of m/z 33, HS+, is either absent or very weak. Thus the HS group is the one that removes the electron ...

Iwakura and Okada 64) interpret the mechanism and kinetics of the fert-amine catalyzed reactions of isocyanates with n-butanethiol and n-dodecanethiol somewhat differently. They found that the catalyzed reaction was strictly first order with respect to the thiol, isocyanate, and... 

The rate of the triethylamine-catalyzed reaction of phenyl isocyanate with n-butanethiol depends on the solvent used and increases in the order benzene, toluene, dibutyl ether, dioxane, methyl ethyl ketone, and nitrobenzene. This solvent effect increased with the ionizing power of the solvent and was the reverse of that observed in the reaction of isocyanates with alcohol.

The moiety transferred will most often be a hydrogen atom, for example, when the transfer agent is a thiol (e.g., n-butanethiol - Scheme 55), a hydroperoxide, the solvent, and so on.
