         3 . A compound of  claim 1  in which Y represents —CF 3 . 
     
     
         4 . A compound of  claim 1  in which R 2  and R 3  independently represent hydrogen, methyl or ethyl. 
     
     
         5 . A compound of  claim 1  having the formula 
       
         
           
           
               
               
           
         
         wherein 
         X represents NO 2 , CN or COOR 4 ; 
         Y represents (C 1 -C 4 )haloalkyl and 
         R 4  represents C 1 -C 3  alkyl. 
       
     
     
         6 . A compound of  claim 1  having the formula 
       
         
           
           
               
               
           
         
         wherein 
         X represents NO 2 , CN or COOR 4 ; 
         Y represents (C 1 -C 4 )haloalkyl 
         R 1  represents (C 1 -C 4 )alkyl; 
         R 2  and R 3  independently represent hydrogen, methyl, ethyl, fluoro, chloro or bromo; 
         R 4  represents C 1 -C 3  alkyl; and 
         n is an integer from 1-3. 
       
     
     
         7 . A compound of  claim 6  in which X represents NO 2  or CN, Y represents CF 3 , R 1  represents methyl or ethyl, R 2  and R 3  independently represent hydrogen, methyl or ethyl, and n is an integer from 1-3. 
     
     
         8 . A composition for controlling insects which comprises a compound of any one of  claims 1 - 7  in combination with a phytologically-acceptable carrier. 
     
     
         9 . A method of controlling insects which comprises applying to a locus where control is desired an insect-inactivating amount of a compound of any one of  claims 1 - 7 . 
     
     
         10 . A process comprising submitting data related to a compound of  claim 1  directly to a governmental or regulatory authority or indirectly through another to a governmental or regulatory authority in order to gain approval for the use or sale or both of said compound.
