| titleOfInvention | Method for the preparation of tetrahydrothiopyran-3-carboxaldehydes |
| abstract | a) basischen Katalysatoren und von Methylenchlorid, aromatischen Kohlenwasserstoffen und/oder 1,1,2-Trichlorethan als Lösungsmitteln und/oder b) in Gegenwart von Carbonsäureamiden hergestellt werden. Preparation of 3-formyl-tetrahydrothiopyrans by hydrogenation of 3-formyl-5,6-dihydro-2H-thiopyrans in the presence of catalysts containing nickel, cobalt, platinum, copper and / or silver, where appropriate the 3-formyl-- 5,6-dihydro-2H-thiopyrans by reacting bis (β-formylethyl) sulfides and / or 3-formyl-4-hydroxy-tetrahydrothiopyrans in the presence of acidic catalysts and, if appropriate, these bis- (β-formylethyl) -suifide and / or 3-formyl-4-hydroxytetrahydrothiopyrane by reacting acroleins with hydrogen sulfide in the presence of a) basic catalysts and of methylene chloride, aromatic hydrocarbons and / or 1,1,2-trichloroethane as solvents and / or b) are prepared in the presence of carboxamides. n n n The compounds which can be prepared by the process of the invention are valuable starting materials for the production of dyes, pharmaceuticals and pesticides. |
