Abstract
Procedimiento para la preparacion de derivados de ácido 1-fenil-pirazolina- 3-carboxílico de la formula general I con olefinas de la formula general II,teniendo Ph, R1, R2, R3, X e Y los siguientes significados: Ph significa fenilo eventualmentesust itudo, R1 significa hidrogeno o alquilo, R2 y R33,independientemente uno de otro, significan hidrogeno, halogeno, cianao, un radical orgánico eventualmente sustituido, o R2 y R3, junto con el átomo decarbono que los lleva, forman unanillo satu rado o parcialmente saturado de 5 o 6 átomos, X significa amino, hidroxi, alcoxi, cicloalcoxi, alquilamino,dialquilamino, alquiloxialquiloxi, trialquilsililoxi y trialquilsililmetiloxi e Y significa cloro o bromo. La reaccion se llevaa cabo en un sistema de dosfases, que consta de una fase orgánica y de una fase acuosa, con utilizacion de una amina impedida estéricamente y eventualmente de otra base. Estos derivadosde ácido 1-fenil-pirazolina-3-carboxílico son empleados comoagentes que protegen a las plantas utiles en cultivos agrícolas y forestales con respectode danos indeseados en el caso de la accion de herbicidas.
