Synthesis, spectra, and reactions of some S-alkylthiophenium salts was written by Acheson, Richard M.;Harrison, Derek R.. And the article was included in Journal of the Chemical Society [Section] C: Organic in 1970.Reference of 18583-55-6 This article mentions the following:
S-Alkylthiophenium, -benzo[b]thiophenium and -dibenzo[b,d]thiophenium salts were prepared by treatment of the corresponding thiophenes with alkyl halides in the presence of AgBF4 or similar reagents. Their uv spectra resemble those of the corresponding sulfoxides and sulfones, rather than those of the parent thiophene. The NMR spectrum of 3-bromo-1-ethylbenzo[b]thiophenium tetrafluoroborate and those of similar compounds show that the Et groups appear as ABX3 systems, which were computer-simulated. The S-alkyl groups are putatively not coplanar with the S-containing rings. In the mass spectrometer the S-alkyl group is very readily lost, but expansion of the thiophene ring also occurs. The salts are powerful alkylating agents. In the experiment, the researchers used many compounds, for example, (2-Chlorobenzyl)triphenylphosphonium chloride (cas: 18583-55-6Reference of 18583-55-6).
(2-Chlorobenzyl)triphenylphosphonium chloride (cas: 18583-55-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Reference of 18583-55-6
