    CPC classification number: C07D209/48

    Abstract: The invention concerns the preparation of 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) (R1 = H, halogen; R2, R3 = halogen; R4 = C-organic rest; R5 = H, CH¿3?) by the reduction of 3-nitrocinnamic acid esters of formula (II) with hydrogen in the presence of a catalyst and the condensation of the 3-aminocinnamic acid esters obtained of formula (III) with a 3,4,5,6-tetrahydrophthalic acid anhydride of formula (IV). 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) are useful active agents in the plant-protection field.

    Abstract: The manufacture of 5-dichloroacetyl-3,3,6-trimethyl-9-oxo-1,5-diazabicyclo[4.3.0]-nonane I by the reaction of 3,3,6-trimethyl-9-oxo-1,5-diaza-bicyclo[4.3.0]nonane II with dichloroacetyl chloride in the presence of a solvent and a base, wherein a) this reaction is carried out in a two-phase system comprising a virtually water-insoluble organic solvent and water, and sodium or potassium hydroxide acting as the base is metered in at a rate corresponding to the rate of consumption of the dichloroacetyl chloride such that the aqueous phase exhibits a pH of from 7 to 9, and b) the resulting product is separated.

    Abstract: 3-Formyltetrahydrothiopyrans are prepared by hydroyenating a 3-formyl-5,6-dihydro-2H-thiopyran in the presence of a catalyst containing nickel, cooalt, platinum, copper and/or silver; if necessary, the 3-formyl-5,6-dihydro-2H-thiopyrans are prepared by converting bis-(.beta.-formylethyl) sulfides and/or 3-formyl-4-hydroxy-tetrahydrothiopyrans in the presence of an acidic catalyst, and, if required, these bis-(.beta.-formylethyl) sulfides and/ or 3-formyl-4-hydroxytetrahydrothiopyrans are prepared by reacting an acrolein with hydrogen sulfide a) in the presence of a basic catalyst and of methylene chloride, aromatic hydrocarbons and/or 1,1,2-trichloroethane as solvents, and/or b) in the presence of a carboxamide. The compounds obtainable by the process according to the invention are useful starting materials for the preparation of dyes, drugs and pesticides.
