    摘要: Fluorine-substituted spirocarboxylic acid benzyl esters of the formula ##STR1## in which R.sup.1 represents hydrogen, cyano or alkyl, alkenyl or alkynyl, with in each case up to 4 carbon atoms,R.sup.2 represents a phenyl radical which is substituted by halogen and/or by optionally halogen-substituted phenoxy, with the proviso that the radical R.sup.2 contains in total at least one fluorine substituent, andR.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represent hydrogen, halogen or alkyl, orR.sup.3 and R.sup.4, taken together, and/or R.sup.5 and R.sup.6, taken together, represent alkanediyl (alkylene) or a fused-on benzo radical,and the C atoms of the 5-member spirocyclic ring are linked to one another either by double bonds or by single bonds, which possess arthropodicidal properties.
