| titleOfInvention | METHOD FOR REGIELECTIVE SYNTHESIS OF DERIVATIVES OF 1-ALKYL-3-HALOGENALKYLPYRAZOL-4-CARBOXYLIC ACID |
| abstract | 1. The method of obtaining derivatives of 1-alkyl-3-haloalkylpyrazole-4-carboxylic acid of the formula (I):! ! in which R1 is selected from the group consisting of (C1-C12) -alkyl, (C3-C8) -cycloalkyl, (C2-C12) -alkenyl, (C2-C12) -alkynyl, (C6-C8) -aryl, ( C7-C19) arylalkyl or (C7-C19) alkylaryl groups, which respectively may be substituted by one or more groups selected from the group consisting of -R ', -X, -OR', -SR ', -NR' 2, -SiR'3, -COOR ', - (C = O) R', -CN and -CONR'2, where R 'is a hydrogen atom or a (C1-C12) -alkyl group; ! R2 is selected from (C1-C4) -alkyl groups which may be substituted with one, two or three halogen atoms selected from F, Cl and Br, or a CF3 group; ! Y is selected from the group consisting of (C = O) OR3, CN and (C = O) NR4R5, where R3, R4 R5, independently from each other, are selected from the group consisting of a hydrogen atom, (C1-C12) -alkyl , (C3-C8) cycloalkyl, (C2-C12) alkenyl, (C2-C12) alkynyl, (C6-C8) aryl, (C7-C19) arylalkyl, or (C7-C19) alkylaryl groups, which, respectively, can be substituted by one or more groups selected from the group consisting of -R ', -X, -OR', -SR ', -NR'2, -SiR'3, -COOR', - (C = O) R ′, —CN and —CONR′2, where R ′ is a hydrogen atom or a (C1-C12) alkyl group; ! or where R4 and R5, together with the nitrogen atom to which they are bonded, can form a five- or six-membered ring; ! including the introduction into the interaction of a 2-acylated derivative of acrylic acid of the formula (II):! ! in which Z1 and Z2, independently from each other, are selected from O and S; ! R6 is selected from the group consisting of (C1-C12) -alkyl, (C3-C8) -cycloalkyl, (C2-C12) -alkenyl, (C2-C12) -alkynyl, (C6-C8) -aryl, (C7- C19) arylalkyl or (C7-C19) alkylaryl groups, which respectively may be substituted by one or more |
