    Abstract: 1=aryl sulfone, arylthio, alkylsulfone, alkylthio, alkyl carbonyl, dialkylphosphono; R2= amino, dialkylamino, lower alkyl, phenyl; R3=lower alkyl; R4= alkoxy, halogen-, nitro- substd. phenoxy, thiophenoxy, lower alkylthio; X=O,S) to prevent rice insect and acarid are prepd. Thus 10g (0.037 mol) 1-methoxycarbonyl-1-phenylsulfonyl-2-(N,Ndimethyl amino) ethene, 6.06g (0.022 mol) N,N-dimethyl guanidine sulfate and 3.52g (0.088 mol) NaOH in the mixed solvent of 60ml EtOH and 15ml H2O are stirred for 8 hr followed by removing solvent and recrystallizing with EtOH to give 7.8g I (R1=II; R2=N (CH3)2).

    Abstract translation: 1 =芳基砜，芳硫基，烷基砜，烷硫基，烷基羰基，二烷基膦酰基; R2 =氨基，二烷基氨基，低级烷基，苯基; R3 =低级烷基; R4 =烷氧基，卤素，硝基。 苯氧基，硫代苯氧基，低级烷硫基; X = O，S），以防止水稻昆虫和螨虫食用。 将10g（0.037mol）1-甲氧基羰基-1-苯基磺酰基-2-（N，N-二甲基氨基）乙烯，6.06g（0.022mol）N，N-二甲基硫酸胍和3.52g（0.088mol）NaOH在 将60ml EtOH和15ml H 2 O搅拌8小时，然后除去溶剂并用EtOH重结晶，得到7.8g I（R 1 = II; R 2 = N（CH 3）2）。

    Abstract: R1=arylsulfon, arylsulfide, alkylsulfon, alkylsulfide alkoxycarbonyl, dialkylphosphono; R2=H, lower alkyl, halogen-, nitro-, lower alkyl-substd. phenyl; R3= lower alkyl; R4=alkoxy, halogen-, nitro-substd. phenoxy, thiophenoxy, lower alkylthio; X=O,S) are prepd. Thus 1g (3.7m mol) 1methoxycarbonyl-1- phenylsulfonyl-2-(N,N-dimethyl amino) ethene in ethanol is cooled. 0.224ml (4.4 m mol) methylhydrizine is dropadded to the mixt. The reaction product is stirred for 9 hr followed by removing solvent to give I (R1=II, R2=H).
