The title compounds were synthesized in one pot from lithiated 1-propa-1,2-dien-1-yl-, 1-prop-2-yn-1-yl-, and 1-methyl-2-prop-1-yn-1-yl-1<i>H</i>-pyrroles, isothiocyanates, and methyl iodide. Under electron impact, all compounds formed stable molecular ions (<i>M</i><sup>+<b>·</b></sup>, <i>I</i><sub>rel</sub> 100%) which underwent fragmentation along two common pathways, C–N bond cleavage in the amine substituent with charge localization on the sulfur atom and generation of [<i>M</i> – R]<sup>+</sup> ions (first pathway) and [<i>M</i> – Me]<sup>+</sup> ions (second pathway). An exception was <i>N</i>-butyl-substituted thiophenamine which showed no [<i>M</i> – Me]<sup>+</sup> ion in the mass spectrum. The stability of these ions depended on the nature of the R substituent. Thus, the [<i>M</i> – R]<sup>+</sup> ion peak (R = Alk) had the highest intensity (<i>I</i><sub>rel</sub> 28–91%), whereas the [<i>M</i> – R]<sup>+</sup> ions (R = Ar) were the least abundant (<i>I</i><sub>rel</sub> 3–8%). In contrast, the intensity of the [<i>M</i> – Me]<sup>+</sup> ion peak in the mass spectra of <i>N</i>-aryl-substituted thiophenamines (<i>I</i><sub>rel</sub> 28–52%) was higher than the intensity of the corresponding ion peak of <i>N</i>-alkyl analogues (<i>I</i><sub>rel</sub> 14–41%), except for <i>N</i>-ethyl-3-(1-methyl-1<i>H</i>-pyrrol-2-yl)thiophen-2-amine, in the spectrum of which the intensity of the [<i>M</i> – Me]<sup>+</sup> ion peak was 57%. The [<i>M</i> – R]<sup>+</sup> and [<i>M</i> – Me]<sup>+</sup> ions derived from all <i>N</i>,<i>N</i>-dimethylthiophen-2-amines had the same <i>m</i>/<i>z</i> value and structure.
