Substituted 1,2,4,6-Thiatriazine 1,1-Dioxides, their Synthesis and Structure

N2-(Methoxycarbonyl)amidines 4 and analogously substituted O-(alkyl)isoureas 5 yield, on reaction with N-alkylsulfamic chlorides, sulfamides 6 and 7 which can be cyclized to give 1,2,4,6-thiatriazin-3-one 1,1-dioxides 8 or 9, respectively.Their structural assignment - with regard to the position of the acidic hydrogen - is supported by X-ray analysis of 9a.The compounds 8 and 9 show herbicidal activity.
