INSECTICIDE MEANS
The invention concerns a new N, N-Dimethyl-O-PYRAZOLYL-more carbaminsäureester than active substances containing insecticide means.
It is already well-known that N, N-Dimethyl-O-PYRAZOLYL-more carbaminsäureester, like e.g. N, N-Dimethyl-o (l-phenyl-3-methyl-pyrazol yl) - and N, N-Dimethyl-o (l-iso-propyl-3-methyl-pyrazol yl) - 5-earbaminsäureester, insecticides characteristics exhibit (VG!. CH-PS Nr.279553 - Chem. Abstraets 47, 10172 a).

Surprisingly, N-Dimethyl-O-PYRAZOLYL-more carbaminsäureester better insecticides show the N which can be used according to invention an effect than the appropriate connections of similar constitution and same direction of action before-well-known from the state of the art. The products in accordance with the invention represent thus a genuine enrichment of the technology.
Connections of the formula (I), in which R, R* and n for the output products of the procedures a) until d) indicated the preferredwise meanings possess (see below) are preferential.

Preferably in it R stand for 1 to 5 carbon atoms for hydrogen as well as for geradkettiges or branched alkyl with I to 8, in particular and for cyanogen ethyl, R” for geradkettiges alkyl with 1 to 5, in particular 1 to 3 carbon atoms and n for 1 or 2.
The Bydroxy pyrazole of the formula (II) one receives by conversion from hydrazine or hydrazine derivatives with A-Alkylthio-aeetessigsäureestern with 0 to 40°C in inert diluents and following oxidation of the 3-Alkylthiomethyl-5-hydroxy-pyrazole with hydrogen peroxide or m-CH, received thereby! orperbenzoesäure, likewise with 0 to 40°G and likewise in presence of diluents.
As Carbaminsäureha] ogenid the formula (III) with procedures {a) and frequently the N used producible in literature-well-known procedures in the technology, N-Bimethyl-carbaminsäurechlorid is preferably used.
With the procedures (C) and (D) when basic materials N which can be used, N-Dimethyl-o (3-alkyltbiomethyl-pyrazol yl) - it is more carbaminsäureester by formula (I) under the condition that n stands for zero, defined. They can be made similar to procedure (A) of the appropriate 3-Alkylthiomethyl -5-hydroxy-pyrazolen and N, N-Dimethyl-carbaminsäurechlorid, preferably become *5 in procedures (C) and (D) connections of the formula (I}, in which n stands for zero, and where R for hydrogen and geradkettiges or branched alkyl with 1 to 8 stands, in particular for 1 to carbon atoms as well as for Cyanoäthyl and stands for R for geradkettiges alkyl with 1 to 5, in particular 1 to 3 carbon atoms, as basic materials assigned.
In procedure (A} and used (B) oxidation center! Hydrogen peroxide and m-chlorine - by benzoic acid well-known connections are and can in literature-well-known procedures be manufactured.
The procedures (A), (B), (C) and (D) for the production of the new N, N-Dimethyl-O-PYRAZOLYL-more carbaminsäureester are accomplished preferentially using diluents, than such are applicable practically all inert organic solvents.
Biezu belong in particular aliphatic and aromatic, if necessary chlorinated hydrocarbons, like gasoline, benzene, toluol, xylene, dichloromethane, chloroform, Tetracblorkohlenstoff, Chlorbenzo] and to o-Bichlorbenzol, ether such as Diäthylund Dibutyläther, tetrahydrofurane and Dioxan, Ketone such as acetone, methyl ethyl, Methylisopropylund Methylisobutylketon as well as nitriles such as Aeetonitril and Propionitril.
For procedures (C) aliphatic carbonic acids e.g. become, like acetic acid. as solvent prefers.
Procedures (A) and (B) are accomplished preferentially using acid acceptors.
As acid acceptors all usual acid bonding agents use can find. Particularly worked satisfactorily alkali carbonates äthylat themselves and - alcoholates, as Natriumund potassium carbonate, Natriumund Kaiiummethylat and/or -, furthermore aliphatic, aromatic or heteroeyelisehe Amiae, for example tri methyl amine, tri methyl amine, Dimethylanilin, Dimethylbenzylamin and Pyridin.
The reactions are accomplished, preferred generally at temperatures between 0 and 80 " C for procedures {a) the range between 20 and 60 " C, for procedures (B), (C) and (D) the range between 5 and 25 “C.
The conversions are accomplished generally with normal print.
For the execution of procedures (A) and (B) the basic materials into äquimolaren quantities are usually used. A surplus or other reaction component does not bring substantial advantages. The conversion is accomplished generally in a suitable diluent in presence of an acid acceptor. After reaction end one pours the mixture in water and vibrates with an organic solvent, e.g. toluol out. The organic phase is then regenerated as usual by washing, drying and Abdestillieren of the solvent.
With procedure (C) the reaction partners are used likewise preferentially into äquimolaren quantities. Those hiebei as diluent used acetic acid is usually abdestilliert after reaction end in the vacuum. Afterwards one adds an organic solvent, z, B. Methylenchlorid and regenerates the organic phase as usual by washing, drying and Abdestillieren of the solvent.
With procedures (D) the m-chlorine-perbenzoesäure used as oxidising agents usually in the surplus is inserted, u.zw between 2 and 3 gets per mol of o (3-AlkylLhiomethyl-pyrazol yl) - 5-N, N-dimethyl-more carbaminsäureester. The conversion is usually not accomplished in solvents mixable with water. One washes then neutrally and regenerates as under (A) and (C) described.
The new connections result partially in the form of oils, which cannot be distilled partially without decomposition, however by so-called “Andesti] lieren”, i.e. by longer heating up under decreased pressure on moderately increased temperatures from the last volatile portions to be released and cleaned in this way. For its characterisation the refractive index serves.
As far as the new products anfaIlen after the Abdestillieren of the solvent in firm form, they are cleaned by recrystallization. For the characterisation the fusion point serves.
As mentions already several times, the new are characterised outstanding insecticides N.N Dimethyl O PYRAZOLYL more carbaminsäureester by an effect.
