    Abstract: The invention relates to a process for the preparation of 2-(2',2',2'-tribromoethyl)-4-chlorocyclo-butan-1-ones of the formula I (I) in which one of the radicals R1 and R2 is methyl and the other is hydrogen or methyl, or R1 and R2 together are an alkylene group having 2 to 4 carbon atoms. The process comprises reacting 2-chloro-4,4,4-tribromo-butyric acid chloride, in the presence of an organic base, with an ethylene, which is disubstituted in the 1-position by the radicals R1 and R2 according to the above definition, to give a 2-(2',2',2'-tribromoethyl)-2-chlorocyclobutan-1-one, and then rearranging this, in the presence of a catalyst, into a 2-(2',2',2'-tribromo-ethyl)-4-chlorocyclobutan-1-one of the formula I. The 2-(2',2',2'-tribromoethyl)-4-chlorocyclobutan-1-ones of the formual I which can be prepared according to the invention are valuable intermediates for the preparation of 2-(2',2'-dibromovinyl)-cyclopropane-1-carboxylic acids and esters thereof having an insecticidal action.

    Abstract: Cyclobutanecarboxylic acid imides of the formula I (I) wherein one of R1 and R6 is hydrogen, methyl or ethyl, and the other is methyl or ethyl, R2 and R3 independently of one another are each hydrogen, fluorine or methyl, or R2 is acetoxy or chlorine while R3 is hydrogen, and wherein R4 is hydrogen, methyl or chlorine, and R5 is hydrogen or methyl, whereby R3 and R4 together can also form an additional bond in the four-membered ring, are suitable for combating various fungi and have a particularly excellent action against Botrytis. They can be produced in an especially advantageous manner by photochemical [2+2] cycloaddition of alkenes or alkines with for example appropriately substituted maleic acid-(3,5-dichlorophenyl)-imides.
