    摘要： 1. Process for the manufacture of N-substituted 1-carbamoyl-3-(3,5-dichlorophenyl)-hydantoins of the formula: ##STR1## in which R.sub.1 =alkyl (C.sub.1 -C.sub.4) or phenyl and R.sub.2 =H or alkyl (C.sub.1 -C.sub.4).2. This process comprises two steps:a. reacting phosgene with 3-(3,5-dichlorophenyl)-hydantoin in an inert organic solvent medium, in the presence of an acid acceptor, in order to form 1-chlorocarbonyl-3-(3,5-dichlorophenyl)-hydantoin, andb. reacting the chlorocarbonyl formed with an amine HNR.sub.1 R.sub.2 in an inert organic solvent, in the presence of an acid acceptor.3. This process makes it possible to obtain the products I, which can be used as agricultural fungicides, with good yields.

    摘要： A racemic or optically active alkyl 2-chloropropionate is prepared, respectively, from a racemic or optically active alkyl lactate by, in a first step, gradually bringing the alkyl lactate into contact with the thionyl chloride, in the presence of an organic base, while maintaining, in the reaction mixture, an excess of thionyl chloride, relative to the amount of alkyl lactate introduced into this mixture, at a temperature below the decomposition point of the chlorosulphinate of the alkyl lactate, which is formed as an intermediate, and then, in a second step, in heating the reaction mixture resulting from the first step at a temperature which is at least equal to the decomposition point of the chlorosulphinate of the alkyl lactate.The alkyl 2-chloropropionates can be used for the manufacture of the racemic or optically active 2-phenoxypropionic acids.
