Abstract: A process for the preparing agrochemical intermediates of formula (I): ##STR1## wherein W is (CH.sub.3 O) CH.CHCO.sub.2 CH.sub.3 or CH.sub.3 O.CH.dbd.CCO.sub.2 CH.sub.3 ; Z.sup.1 is a halogen atom; and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, acetoxy or acyl; the process comprising the steps of:(a) reacting a compound of formula (II): ##STR2## wherein X, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined above, with a compound of formula ROCH.sub.3, wherein R is a metal; and,(b) reacting the product of (a) with a compound of formula (III): ##STR3## wherein Z.sup.1 and Z.sup.2 are halogen atom. A process for the preparation of compounds of formula (II) and compounds of formula (II) themselves. A process for obtaining, in substantially pure form, a compound of formula (II) wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are all hydrogen.

Abstract: Compounds of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, acetoxy or acyl, and processes for preparing the same.

Abstract: Benzodifurantriones of Formula (1): ##STR1## in which W is unsubstituted or substituted aryl, a process for their preparation via dioxo intermediates and processes for their conversion into benzodifuranone dyes and compounds of Formula (7): ##STR2## are provided wherein R.sup.3 is --H, --COR.sup.2, --SO.sub.2 R.sup.2 -- which R.sup.2 is alkyl, cycloalkyl, aryl or aralkyl and R.sup.4 is --COOR.sup.2, --CONRR.sup.1 in which R and R.sup.1 each independently is --H, alkyl, cycloalkyl, aryl or aralkyl; --COOH or the alkali metal, alkaline earth metal or ammonium salts thereof; or --COX.sup.2 -- which X.sup.2 is halo.
