Abstract (en)
[origin: WO0248111A2] 4-haloalkyl nicotine nitriles (I) are suitable for use as intermediate products in the production of pesticides and can be obtained by means of a method which provides that a) 3-amino-1-haloalkyl-2-propen-1-one R<F>-C(O)-CH=CH-NH2 (II) is reacted with a compound of formula (III) to (VII), (R<1>Z)CH=CH-CN (III) (R<1>Z)2CH-CH2-CN (IV) Hal-CH=CH-CN (V) Hal2CH-CH2CN (VI) HC=C-CN (VII) in a condensation reaction, R<F> meaning (C1-C4)-haloalkyl R<1> alkyl, Hal Cl or Br and Z meaning O, S, NR<1> or OCO, and in the case of formula (IV), the two radicals Z being able to have the aforementioned meanings, independently of each other; to produce a compound of formula (VIII), (IX) and/or (X), R<F>-C(O)-CH=CH-NH-CH=CH-CN (VIII) R<F>-C(O)-CH=CH-NH-CH(ZR)-CH2-CN (IX) R<F>-C(O)-CH=CH-NH-CH(Hal)-CH2-CN (X), R, Z and Hal having the meanings given above, and subjecting the product of the reaction b) to a ring closure reaction.
