Abstract
La presente invención se refiere a un proceso para la preparación de ésteres ciclopropancarboxílicos substituidos, representados por la siguiente fórmula general:(ver figura). en donde R1, R2, R3 y R4, los cuales pueden ser iguales o diferentes, cada uno presenta un átomo de hidrógeno o un grupo de hidrocarburo, R1 y R2 ó R1 y R3 pueden estar unidos para formar un anillo junto con los átomos de carbono a los cuales están unidos, R3 es un residuo de alcohol e Y y Z los cuales pueden ser iguales o diferentes cada uno representa un átomo de hidrógeno o de halógeno, el cual comprende reaccionar bajo calentamiento, preferentemente a una temperatura desde 100ªC., un 1-halogen-3-alquen-2-o1 representando por la fórmula general: (ver figura). En donde R1, R2, R3 Y y Z son como se definió anteriormente, y X es un átomo de ahalógeno seleccionado de F, Cl, Br, y I, con un éster orto- carboxílico representado por la fórmula general siguiente:R4 - CH2 - C ( OR5 )3. En donde R4 y R5 son como se refinieron anteriormente, y tres de los grupos R5 pueden ser iguales o diferentes,obteniendose un éster de ácido gamma-halogen-delta-insaturado carboxílico, representado por la siguiente fórmula general: (ver figura). En donde R1, R2, R3, R4, R5, X, Y y Z tienen las definiciones anteriores y tratar el producto resultante con una substancia básica.The present invention relates to a process for the preparation of substituted cyclopropancarboxylic esters, represented by the following general formula: (see figure). where R1, R2, R3 and R4, which may be the same or different, each have a hydrogen atom or a hydrocarbon group, R1 and R2 or R1 and R3 may be linked to form a ring together with the atoms of carbon to which they are attached, R3 is an alcohol residue and Y and Z which can be the same or different each represent a hydrogen or halogen atom, which comprises reacting under heating, preferably at a temperature from 100ºC., a 1-halogen-3-alken-2-o1 representing by the general formula: (see figure). Wherein R1, R2, R3 Y and Z are as defined above, and X is an halogen atom selected from F, Cl, Br, and I, with an orthocarboxylic ester represented by the following general formula: R4-CH2 - C (OR5) 3. Where R4 and R5 are as previously defined, and three of the R5 groups can be the same or different, obtaining a gamma-halogen-delta-unsaturated carboxylic acid ester, represented by the following general formula: (see figure). Wherein R1, R2, R3, R4, R5, X, Y and Z have the above definitions and treat the resulting product with a basic substance.
