Abstract: The changes of the biologic activity were investigated by adding 0,0-dialkyldithiophosphoric acids rest to the N-methyl group of endo-cis-N-methylbicyclo[1.2.2]hept-5-ene-2,3-dicarboxylic acid imide. Derivatives resulted from this reaction become insecticide active and so they are not synergists in full sense of the word. By the addition of O,0-dialkyldithiophosphoric acid to the double bond in the position C₍₅₎ of the substances in question, both the pseudosynergic and insecticide effects werelowered. Endo-cis-N-[S-(O,O-dialkyldithiophosphoric)methyl]-3-carboxamido-5-[S-(O,O-dialkyldithiophosphoric)]bicyclo[1.2.2]heptane-2-carboxylic acid methyl esters are more active than the unesterified ones.
