Definitions
- the present invention relates to new derivatives of 2- (2,2-dihalovinyl) -3,3-dimethylcyclopropane carboxylic acid, a process for their preparation and intermediates for their preparation.
- the cyclopropanecarboxylic acid derivatives of the general formula (I) serve as intermediates for the preparation of the known cyclopropanecarboxylic acids on which they are based, which in turn are intermediates for the preparation of known insecticides.
- the cyclopropanecarboxylic acids are obtained by hydrolyzing the compounds of the general formula (I) acidic or alkaline under suitable conditions (Houben-Weyl, Methods of Organic Chemistry, Volume VIII, p. 432 (1952) and Methodicum Chimicum, Volume 5, p. 572 (1975)).
- cyclopropanecarboxylic acid derivatives of the general formula (1) represents a decisive improvement in the process for the preparation of cyclopropanecarboxylic acids, starting from the corresponding cyclopropanecarboxylic acid nitrile.
- the step of cyclopropanecarboxylic acid nitrile which is difficult to saponify in low yield and in low yield is thereby avoided .
- the use of the new substances according to the invention leads to a process which has the decisive advantage that the synthesis of the insecticidally active 2- (2,2-dihalovinyl) -3,3-dimethylcyclopropanecarboxylic acid esters such as 2- (2,2-dichlorovinyl) ) -3,3-dimethylcyclopropanecarboxylic acid-3-phenoxy-benzyl ester is easier and possible in better yields than from the corresponding nitriles.
- Atoms such as ethylene or trimethylene are furthermore the rest of the formula (b), where R 5 is hydrogen, alkyl radicals having 1 to 4 carbon atoms and R 6 is hydrogen, alkyl radicals having 1 to 4 carbon atoms, aryl such as Phenyl, hydroxyl, alkoxy radicals with 1 to 4 carbon atoms or amino and R 5 and R 8 also represent parts of a ring such as tetramethylene, pentamethylene or ⁇ CH 2 ⁇ CH 2 ⁇ O ⁇ CH 2 ⁇ CH 2 -, furthermore for the rest of the formula (c), where R 7 is hydrogen, alkyl radicals having 1 to 4 carbon atoms, aryl such as phenyl, alkylamino having 1 to 4 carbon atoms, dialkylamino having 2 to 8 carbon atoms, hydroxyl, alkoxy radicals 1 to 4 carbon atoms and R 8 is hydrogen and alkyl radicals having 1 to 4 carbon atoms and R 9 is hydrogen, alkyl radicals having
- the individual reaction stages can be combined in one process in such a way that the purification and isolation of the pure intermediates can be dispensed with.
- Y has the meaning given above, optionally in the presence of a diluent with tetrahalomethane in the presence of a catalyst.
- tetrahalomethanes are carbon tetrachloride, bromotrichloromethane or tetrabromomethane.
- Preferred compounds of general formula (III) are those which lead to the preferred compounds of formula (11).
- the addition of the tetrahalomethanes to the compounds of the formula (III) is carried out in the temperature range from 50 to 120 ° C., preferably 70 to 100 ° C., using catalysts such as dibenzoyl peroxide, azobisisobutyronitrile, copper or iron salts.
- inert organic solvents such as hydrocarbons, ethers, nitriles, esters, ketones are suitable as diluents.
- the process for the preparation of the 2 (2,2-dihalovinyl) -3,3-dimethylcyclopropanecarboxylic acid derivatives according to the invention is carried out by the action of at least two moles of base on the compounds of the formula II and gives the compounds of the invention with cyclization and ⁇ -elimination. Cyclization and ⁇ -elimination can be carried out either sequentially or simultaneously.
- Bases include tertiary amines, for example pyridine, triethylamine, dimethylaniline, benzyldimethylamine, N-methylpiperidine, 1,8-diazabicyclo (5,4,0) -undecene, alkali metal alkolates, for example sodium methylate, sodium ethylate, potassium t-butoxide and also alkali metal hydroxides such as Sodium hydroxide or potassium hydroxide and alkali and alkaline earth carbonates.
- tertiary amines for example pyridine, triethylamine, dimethylaniline, benzyldimethylamine, N-methylpiperidine, 1,8-diazabicyclo (5,4,0) -undecene
- alkali metal alkolates for example sodium methylate, sodium ethylate, potassium t-butoxide and also alkali metal hydroxides such as Sodium hydroxide or potassium hydroxide and alkali and alkaline
- Suitable diluents are alcohols such as methanol, ethanol or t-butanol, ethers such as dioxane or diethyl ether, and polar solvents such as acetonitrile, dimethylformamide, dimethyl sulfoxide or hexamethylphosphoric triamide.
- reaction temperatures can be varied within a wide range. Generally one works between room temperature and 120 ° C, preferably between 40 ° and 80 ° C.
- Y represents the oxazoline radical of the general formula IV in which
- R 12 ⁇ R 15 independently of one another represent hydrogen, alkyl, aralkyl, aryl or together with the adjacent C atoms can form a carbocyclic ring are new.
- R 12 ⁇ R 15 have the meaning given above, if appropriate at temperatures of 150-200 ° C in the presence of a catalyst and a diluent.
- R 12 ⁇ R 15 de oxazoline radical of the general formula IV independently of one another are hydrogen, alkyl having 1-4 C atoms, aralkyl having 7-9 C atoms or phenyl, possibly by halogen, alkoxy or Phe noxy is substituted, where R 12 and R 13 or / and R 14 and R 15 can form an alkylene chain with 4-6 C atoms and R 12 with R 14 or R 15 can form an alkylene chain with 3-4 C atoms .
- the present invention is illustrated by the following examples.
- the formation of the residue Y i.e. the carboxylic acid derivative group, starting from 4-cyano-3,3-dimethyl-1-or 3,3-dimethyl-4-pentenoic acid.
