[Application of high resolution mass spectra to the analysis of alpha-thiocarbonylthioformamides].

Acetophenone and its derivatives reacted on thionyl chloride to form an intermediate, which can react on the secondary aminnes to form alpha-carbonylthioformamides (1a-1f), followed by sulfurization with lawesson reagent to give target compounds alpha-thiocarbonylthioformamides (2a-2f). Compounds 2a-2f are the deep-red or deep-green crystals because there are two thiocarbonyl groups in the molecule, and they can be used as far-infraed adsorbent dyes, laser-Q switch and organic conductors. Moreover, they are very important intermediates, can react on reagents with amino or diamino groups to produce a variety of acyclic or heterocyclic compounds, which can be used as pesticides and medicines.
