Abstract:
Pyrryl-2-acetonitriles corresponding to the formula ##STR1## in which R.sub.1 stands for hydrogen or an alkyl group having 1-4 carbon atoms prepared from dialkyl-(pyrryl-2-methyl)-amine corresponding to the formula ##STR2## in which R.sub.1 is defined as above and R.sub.2 and R.sub.3 stand for alkyl groups having 1-4 carbon atoms, are alkylated with alkyl halides such as methyl chloride or methyl bromide to form the corresponding trialkyl-(pyrryl-2-methyl)-ammonium chloride quaternary salts and then reacted with an aqueous solution of alkali cyanide in the presence of a water-immiscible solvent under conditions which provide more economical utilization of reactants and process equipment.
Abstract:
Carboxylic acid esters of the formula (I), ##STR1## wherein X is a hydrogen atom, or a C.sub.1 -C.sub.3 alkyl or a C.sub.1 -C.sub.3 alkoxyl group or a halogen atom linked to the meta or para position and R.sub.1 is a group of the formula (II) or (III), ##STR2## wherein R.sub.2 is a hydrogen atom or a methyl group, and when R.sub.2 is a methyl group R.sub.3 is also a methyl group, and when R.sub.2 is a hydrogen atom R.sub.3 is a group of the formula, ##STR3## (wherein R.sub.5 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, vinyl or a C.sub.1 -C.sub.3 alkoxymethyl group, R.sub.6 is a hydrogen or halogen atom or a methyl group, or, taken together, R.sub.5 and R.sub.6 may form a tetramethylene group by connecting together at ends thereof), R.sub.4 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxyl or 3,4-methylenedioxy group, n is 1 or 2 and Y is a isopropyl or cyclopropyl group. These carboxylic acid esters are produced by reacting the reactive derivatives of a carboxylic acid represented by the formula, ##STR4## wherein R.sub.1 is a group of the formula (II) or (III), ##STR5## wherein R.sub.2, R.sub.3, R.sub.4, n and Y are as defined above, and Z is a halogen atom, with an alcohol of the formula (IV), ##STR6## wherein X is as defined above, in the presence of an acid-binding agent. These carboxylic acid esters are useful as insecticides and acaricides.
