A process for the preparation of Derivatives of Carbo - xiamidina

摘要

Process for the preparation of Derivatives of carboxiamidina.Involves reacting a compound of formula (ii) with a compound of formula R5 - S - W to obtain carboxiamidina Derivatives of formula (i), where x1 and x2 are each h, halogen, Methyl or trifluormetilo, with the condition that cannot be h at the same time, R1 and R3 are each h, Hal Ogeno, Nitro, haloalquilo C 1 to 6 and others; R2 is H, alkyl, halogen, Nitro, C 1 to 8Haloalquilo C 1 to 3 (C 1-6 alkoxy carbonyl), and others; and R5 is C 1 to 18 alkyl, cycloalkyl and other C 3 to 8; and W represents a Halogen or a radical succinimido. The reaction is carried out in an organic Solvent such as benzene, toluene and other, temperature of 0 to 50jc and during 5 to 10 hours. They are useful as insecticides.
