    Abstract: Substd. salicylic acid alkyl ester derivs. of formula (I) are new. R1 = 1-6C alkyl; R2 = H or 1-4C alkyl; R3 = N-bonded imidazolyl or triazolyl, each opt. substd. on the C atoms with 1-3 gps. chosen from 1-4C alkyl, 1-4C alkylthio, halogen or Ph, or R3 is an opt. mono, di or tri-substd. (or mono to penta-halo substd.) phenyl thio gp. of formula (i). R4-R8 = H, halogen, CN, NO2, 3-6C alkenyl, 3-6C alkenyloxy, 3-6C alkynyloxy, 3-6C alkynyloxy (these last 4 gps. opt. substd. by 1-5 halogen atoms), di-(1-4C)alkylamino, 3-8C cycloalkyl (opt. substd. by 1-3 1-4C alkyl gps.), 1-10C alkoxycarbonyl, 1-4C alkylthio, PhO (opt. substd. by 1-5 halogen atoms and/or 1-3 of the following 1-4C alkyl, 1-4C haloalkyl, 1-4C haloalkoxy, 1-4C alkoxy or 1-4C alkylthio), 1-10C alkyl or 1-10C alkoxy (these last 2 opt. substd. by 1-5 halogen atoms and/or one of the following: 1-4C alkoxy, 1-4C alkylthio, Ph or PhO (these last 2 themselves opt. substd. by 1-5 halogen atoms and/or 1-3 of the following gps. 1-4C alkyl, 1-4C haloalkyl, 1-4C haloalkoxy or 1-4C alkylthio)). USE/ADVANTAGE - (I) are intermediates in the prepn. of salicylic acid derivs. with herbicidal and/or bioregulating properties. (I) provide a cheaper route for the synthesis of these biologically active cpds., in that the starting materials 2-chloro-3-alkoxy-carbonyl -2,4-hexadiene-carboxylic acid esters (II) for the prepn. of (I) are readily available. The need to use the expensive starting material 2-fluoro-6-methoxy benzonitrile is avoided.

    Abstract: Process for the preparation of cis-2-(1H-1,2,4-triazol-1-ylmethyl)-2-(halophenyl)-3-(halophenyl)oxira ne I by epoxidation of Z-3-(1H-1,2,4-triazol-1-yl)-2-(halophenyl)-1-(halophenyl)propene II, in which halogen is in each case fluorine, chlorine or bromine, by reaction of the crude epoxidation product with one or more reducing agents, in which the reducing agent is added to the reaction mixture in a substantially higher amount than is necessary for destroying any peroxide compounds present.

    IPC: C07F9/30

    Abstract: Process for the preparation of bis(aminomethyl)phosphinic acid I or acidic or basic salts thereof by reacting an N-hydroxymethylcarboxamide of the general formula II in which R denotes an unsubstituted or substituted alkyl, cycloalkyl, aralkyl or aryl radical, with a trivalent phosphorus-halogen compound, if appropriate in the presence of an alkali bromide, alkaline earth bromide, ammonium bromide, alkali metal iodide, alkaline earth metal iodide or ammonium iodide, to give bis(aminomethyl)phosphinic acid derivatives of the general formula III and these are converted into bis(aminomethyl)phosphinic acid in the form of its acidic or basic salts by hydrolytic elimination of the acyl radicals and, if appropriate, liberating the free acid I.
