Abstract: Cyclopropane derivs. (I; Hal = halogen, R1 = H, alkyl or Ph, R2, R3 = H or alkyl, R4 = CN, COSMe, CO2H, substituted NH2), used as fungicides, e.g., against pyricularia oryzae on rice plants, were prepd. by reaction of R1R2C = CR3-CO2R with Cl3COO2Na or X3CHgPh producing dihalocarben. Cl3COO2 Na or Cl3CHgPh was added to Me2C:CHCO2Me and the mixt. heated 2hr at 115≦̸C to give I (X = Cl, R1 = R2 =Et, R3 = H, R4 = CO2Et).
