    Description / Table of Contents: Acylations of Alkyl Thiocyanates.Alkyl thiocyanates 3 react with acyl chloride/SbCl5 to give N-benzoyl-C-(methylthio)nitrilium hexachloroantimonate(V) (4) or the 2-aryl(alkyl)-4,6-bis(alkylthio)-1,3,5-oxadiazinium hexachloroantimonates(V) 6. Reactions of 6 with water yield the isothiourea derivatives 7 or the thioallophanic acid derivatives 15, with amines the derivatives 8 and 17 of guanidine are formed.
    Notes: (Alkyl)thiocyanate 3 reagieren mit Acylchlorid/SbCl5 zu N-Benzoyl-C-(methylthio)nitrilium-hexachioroantimonat(V) (4) oder zu den 2-Aryl(Alkyl)-4,6-bis(alkylthio)-1,3,5-oxadiazinium-hexachloroantimonaten(V) 6. Die Umsetzungen von 6 mit Wasser ergeben die Isothioharnstoffderivate 7 oder die Thioallophansäurederivate 15, mit Aminen bilden sich die Guanidinderivate 8 und 17.
