Abstract

LAS 2- Y 4- (DICLOROMETIL) PIRIDINAS CONTENIENDO SUSTITUYENTES PRIVADOS DE ELCTRON EN EL ANILLO, SE PREPARAN POR REACCION DE LAS CORRESPONDIENTES 2- O 4-HALOPIRIDINAS CON EXCESO DE CLOROFORMO EN PRESENCIA DE UNA FUERTE BASE EN UN MEDIO QUE CONTENGA UN DISOLVENTE 2 DIPOLAR O UN CATALIZADOR DE TRANSFERENCIA DE FASE. EL 3-CLORO-5-(TRIFLUOROMETIL)-2-(DICLOROMETIL) PIRIDINA, POR EJEMPLO, SE PREPARA REACCIONANDO 2,3-DICLORO-5-(TRIFLUOROMETIL) PIRIDINA CON CLOROFORMO EN PRESENCIA DE HIDROXIDO DE SODIO Y N-METILPIRROLIDONA. LAS 2-(DICLOROMETIL) PIRIDINAS SUSTITUIDAS SON UTILES COMO PESTICIDAS AGRICOLAS Y COMO PRODUCTOS INTERMEDIOS EN LA PREPARACION DE PESTICIDAS AGRICOLAS.
