摘要:Fungicides having thiophene rings may be made from the intermediate compound 3-carbomethoxy-4,5-dimethylthiophene. That compound, and related compounds, may be produced by reacting an alpha mercaptoketone, e.g., 3-mercapto-2-butanone, with an acrylate, e.g., methyl-3-methoxy acrylate, in the presence of an alkoxide base, e.g., NaOMe, to form the substituted tetrahydrothiophene, followed by conversion to the aromatic thiophene with an acid treatment. The substituted tetrahydrothiophene is a novel compound.

摘要:Hydroxamic acid derivatives of the formula in which Y represents oxygen or sulfur, R¹ represents hydrogen, alkyl or alkoxy, R² represents hydrogen, alkyl, alkoxy or halogen, R³ represents hydrogen, alkyl, alkoxy or halogen, R < 4> represents hydrogen or alkyl, R <5> represents alkyl, alkenyl, alkynyl or alkoxyalkyl, R <6> represents hydrogen, alkyl, alkenyl, alkynyl or alkoxyalkyl or R <4> and R <5> together represent one Alkylene chain, or R 5 and R 6 together represent an alkylene chain, provided Y is oxygen and Z is halogen, a process for their preparation and their use as herbicides. N-phenylglycine derivatives of the formula in which Y, R¹, R², R³, R <4>, R <5> and R <6> have the meanings given above, several processes for their preparation and their use as intermediates for the synthesis of the substances of formula (I).
