    Description / Table of Contents: s-Triazinethiones, II. Synthesis by Treatment of N-unsubstituted Amidino Compounds with Aroyl IsothiocyanatesTriazinethiones of the type 1-5 were synthesized by reaction of amidines, isoureas, isothioureas or guanidines with aroyl isothiocyanates. Combination of weakly basic amidino compounds with weakly electrophilic isothiocyanates gave good yields. Otherwise formation of aroylamidines predominated. Intermediates were observed only with sterically hindered isothiocyanates. Benzoyl and thiobenzoyl isocyanates reacted similarly to give s-triazinones.  -  Some chemical and physical properties of the new compounds are listed.
    Notes: Amidine, Isoharnstoffe, Isothioharnstoffe und Guanidine wurden mit Aroylsenfölen zu Triazinthionen 1-5 umgesetzt. Gute Ausbeuten wurden erzielt bei Kombination von schwach basischen Amidinoverbindungen mit wenig elektrophilen Senfölen. Im andern Fall trat die Bildung von Aroylamidinen in den Vordergrund. Zwischenstufen der Synthese wurden nur bei sterisch gehinderten Senfölen beobachtet.  -  Benzoyl- und Thiobenzoyl-isocyanat reagierten entsprechend zu Triazinonen. Einige chemische und physikalische Eigenschaften der Triazinthione werden mitgeteilt.
