Abstract

"PROCESSO PARA PRODUZIR 5-[(4-CLOROFENIL)METIL]-2,2-DIMETILCICLOPENTANONA". Um processo para produzir 5-[(4-clorofenil)metil]-2,2-dimetilciclopentanona de acordo com a presente invenção, compreende: reagindo metil éster de ácido 1-[(4-clorofenil)metil]-3-metil-2-oxo-ciclopentanocarboxílico ou etil éster de ácido 1-[(4-clorofenil)metil]-3-metil-2-oxociclopentanocarboxílico com hidreto de sódio e metil haleto; e hidrolisando o metil éster de ácido 1-[(4-clorofenil)metil]-3,3-dimetil-2-oxociclopentanocarboxílico ou etil éster de ácido 1-[(4-clorofenil)metil]-3,3-dimetil-2-oxociclopentanocarboxílico. Tal processo da presente invenção pode produzir 5-[(4-clorofenil)metil]-2,2-dimetilciclopentanona como um intermediário importante de um fungicida agricultural ou horticultural, por exemplo, Metconazol com uma alta qualidade em um alto rendimento.
