The present invention relates to a process for the preparation of compounds of formula (I) wherein the substituents are as defined in claim, by a) reaction of a compound of formula (II) to form a compound of formula (III) b) reaction of that compound in the presence of a base to form a compound of formula (IV) c) conversion of that compound in the presence of a reducing agent into a compound of formula (I). 

Process for the production of 2(2-aminophenyl)-bicylopropane derivatives

The present invention relates to a process for the preparation of compounds of formula I wherein the substituents are as defined in claim 1, by conversion of a compound of formula II reaction of that compound with a compound of formula IVX&#x2014;C(O)&#x2014;Q,&#x2003;&#x2003;(IV)wherein X is a leaving group, to form a compound of formula V and treatment of that compound in the presence of a base with catalytic amounts of cyanide ions.

Process for the preparation of cyclic diketones

Novel pyrrole derivatives of formula I wherein

Trifluoromethylpyrrolecarboxamides and trifluoromethylpyrrolethioamides as fungicides

Pyrrolecarboxamides and pyrrolethioamides as fungicides

The present invention relates to a process for the preparation of bicyclic 1,3-diketone salts of formula Iwherein R, R, Rand Rare each independently of the others hydrogen or C-Calkyl; A and E are each independently of the other C-Calkylene, which may be substituted once or up to four times by a C-Calkyl group, and Mis an alkali metal ion, alkaline earth metal ion or ammonium ion, by oxidation of a compound of formula IIto a compound of formula IIIand subsequent conversion to a compound of formula I either in the presence of a base and a catalytic amount of a cyanide or in the presence of an alkali metal alcoholate or alkaline earth metal alcoholate, and to novel bicyclic enol lactone intermediates of formula III for use in that process.

Process for the preparation of bicyclic diketone salts

The present invention relates to a process for the preparation of compounds of formula I:wherein the substituents are as defined in claimby conversion of a compound of formula II:reaction of that compound with a compound of formula IV:X&#x2014;C(O)&#x2014;Q&#x2003;&#x2003;(IV),wherein X is a leaving group, to form a compound of formula V:and treatment of that compound in the presence of a base with catalytic amounts of cyanide ions.

Novel pyrrole derivatives of formula (I) wherein X is oxygen or sulfur; R is C -C alkyl unsubstituted or substituted, with the exception of CF ; C -C cycloalkyl unsubstituted or substituted; or halogen; R is hydrogen, C -C alkyl unsubstituted or substituted, C -C alkoxy unsubstituted or substituted, cyano or halogen; R is C -C alkyl unsubstituted or substituted; and A is orthosubstituted aryl; orthosubstituted heteroaryl; bicycloaryl unsubstituted or substituted; or bicycloheteroaryl unsubstituted or substituted. The novel compounds have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms.
