Abstract

Compuestos de sulfuro y método de produccion de derivados tiocromano y derivados dihidrobenzo[b]tiofeno, siendo dichos sulfuros representados por la formula (1), donde R1 y R2 son independientemente cada uno halogeno o C1-4 alquilo; R3, R4, R5, R6 y R7 son independientemente cada uno hidrogeno o C1-4 alquilo; y R5 y R6 o R6 y R7 pueden unirse entre sí a través de cualquier átomo del carbono formar un anillo de hidrocarburo de 3 a 7 miembros. El compuesto del sulfuro es un material inicial util para una produccion facilitada y con bajo costo del derivados 6-acetiltiocromano, derivados 5-acetildihidro-benzo[b)tiofeno, derivados tiocromano-6-ácido carboxílico y derivados dihidrobenzo[b]tiofeno-5-ácidos carboxílicos que son los intermediarios utiles para producir derivados del pirazol como herbicidas activos y derivados de ciclohexanoediona. También descriptos son los métodos que no afectan al medio ambiente para producir los derivados tiocromano-6-ácidocarboxílicos y los derivados dihidrobenzo[b]tiofeno-5-ácido carboxílico a costos bajos y de manera industrialmente ventajosa.Sulfide compounds and method of production of thiochroman derivatives and dihydrobenzo [b] thiophene derivatives, said sulfides being represented by formula (1), where R1 and R2 are each independently halogen or C1-4 alkyl; R3, R4, R5, R6 and R7 are each independently hydrogen or C1-4 alkyl; and R5 and R6 or R6 and R7 can be linked together through any carbon atom to form a 3- to 7-membered hydrocarbon ring. The sulfide compound is a useful starting material for a facilitated and low-cost production of 6-acetylthiochroman derivatives, 5-acetyldihydro-benzo [b) thiophene derivatives, thiochroman-6-carboxylic acid derivatives and dihydrobenzo [b] thiophene-5 derivatives -carboxylic acids that are useful intermediates to produce pyrazole derivatives as active herbicides and cyclohexanedione derivatives. Also described are methods that do not affect the environment to produce thiochroman-6-carboxylic acid derivatives and dihydrobenzo [b] thiophene-5-carboxylic acid derivatives at low costs and in an industrially advantageous manner.
