Abstract: The present invention relates to novel alkoxy enones and enamino ketones, and to a novel process for preparation thereof. Alkoxy enones and enamino ketones are valuable intermediates for preparation of pyrazoles and anthranilamides, which can be used as insecticides.

Abstract: The present invention relates to a process for the regioselective synthesis of 1-alkyl-3-halo-alkylpyrazole-4-carboxylic acid derivatives by cyclization of 2,3-disubstituted acrylic acid derivatives, and to the hydrazones formed as intermediates in the process.

Abstract: The present invention relates to a process for preparing fluoroalkyl nitriles by reacting fluorinated carboxamides with halides and fluorinated carboxylic acids.

Abstract: The present invention relates to a process for preparing hydrochloride-free 2-dihaloacyl-3-aminoacrylic esters by reacting acid fluorides with dialkylaminoacrylic acid derivatives.

Abstract: Nicotinamide compounds of the formula (1) and processes for the preparation thereof are described.

Abstract: A process is described for preparing dioxazine derivatives of the formula (1) and corresponding intermediates.

Abstract: The invention relates to a process for preparing alkyl dihaloacetoacetates of the formula (I) by reacting ?,?-dihaloamines of the formula (III) with acetic esters of the formula (II) in the presence of bases.

Abstract: The invention relates to a process for preparing 2,4-dihydroxyphenyl 4-methoxybenzyl ketones of the formula (I) by Friedel-Crafts acylation in hydrogen fluoride (HF). 2,4-Dihydroxyphenyl 4-methoxybenzyl ketones of the formula (I) in which R1 and R2 are each hydrogen, chlorine, fluorine, bromine, iodine, CF3, methyl, optionally substituted alkoxy, —OCF3, —C(CH3)3, —CH2(CH3)2, —CH(CH3)2, R3 is hydrogen, Cl, F, Br, optionally substituted alkyl, optionally substituted alkoxy, —C(CH3)3, and X is hydroxyl, F, Cl, Br, optionally substituted alkoxy, are obtained in high yield and high purity by reacting phenylacetic acid derivatives of the formula (II) with phenols of the formula (III) in liquid hydrogen fluoride (HF).

Abstract: The current invention describes a one-step process for the synthesis of 2-fluoropropionates from lactic acid ester derivatives using TFEDMA.

Abstract: The invention relates to a process for preparing aminoglycol by reacting ketoximes with ethylene oxide under basic conditions to give a substituted 2-hydroxyethyl ketoxime and subsequently reacting the latter with an acid to give aminoglycol.

Abstract: The present invention relates to a novel process for preparing known 5-fluoro-1,3-dialkyl-1H-pyrazole-4-carbonyl chlorides which can be used as starting materials for active fungicidal ingredients.
