INSECTICIDES CONTAINING AS ACTIVE SUBSTANCE DERIVATIVES SUBSTITUATED BY VINYL GROUP CYCLOPROPHAN CARBONIC ACID ESTHER AND PROCESS FOR PRODUCTION OF THE ACTIVE SUBSTANCE

摘要

All stereoisomeric forms and mixtures of stereoisomers of compounds of the formula I wherein X is selected from the group consisting of oxygen, sulfur, sulfoxide and sulfone, R1 and R3 are individually selected from the group consisting of optionally unsaturated alkyl of 1 to 7 carbon atoms and optionally unsaturated cycloalkyl of 3 to 7 carbon atoms optionally substituted with at least one halogen and optionally interrupted with at least one heteroatom and aryl and aralkyl of 6 to 18 carbon atoms and R2 is the residue of a R2OH alcohol used in pyrethrinoids synthesis having pesticidal activity and their preparation and novel intermediates.
