Abstract

Disclosed are novel metal salts of 1,1,5,5-tetrasubstituted dithiobiurets of the formula ##STR1## in which R 1 , R 2 , R 3 and R 4 , when taken independently of each other are selected from the group consisting of C 1 -C 18 alkyl, C 6 -C 12 aryl, C 3 -C 12 cycloalkyl, and these radicals substituted by at least one member of the group consisting of hydroxyl, C 1 -C 4 alkyl, C 1 -C 8 acyl, halo and nitro, and R 1 and R 2 , when taken together along with the nitrogen to which they are bonded, and . .R 3 .!. .Iadd.R 3 .Iaddend.and R 4 when taken together with the nitrogen to which they are bonded, are selected from the group consisting of N-morpholinyl, N-piperidyl, N-pyrrolidyl and N-aziridinyl. The compounds are useful as population control agents.

Claims

exact text as granted — not AI-modified
What I claim and desire to protect by letters Patent is: 
     
       1. A metal salt of a 1,1,5,5-tetrasubstituted dithiobiuret of the formula: ##STR11## in which R 1 , R 2 , R 3  and R 4  independently of each other are selected from the group consisting of C 1  -C.sub. 18 alkyl, C 5  -C 12  aryl, C 3  -C 12  cycloakyl and these radicals substituted by at least one member of the group consisting of hydroxyl, C 1  -C 4  alkyl, C 1  -C 8  . .aryl.!. .Iadd.acyl.Iaddend., halo and nitro. 
     
     
       2. A compound according to claim 1 in which R 1 , R 2 , R 3  and R 4  are each methyl, and the metal of said metal salt is selected from the group consisting of the alkali metals, the alkaline earth metals, zinc, cadmium, tin, mercury, copper, nickel, chromium, iron, silver, manganese, and beryllium. 
     
     
       3. A compound according to claim 1 in which R 1 , R 2 , R 3  and R 4  are each ethyl. 
     
     
       4. A compound according to claim 1 in which the metal is zinc. 
     
     
       5. A compound according to claim 1 in which the metal is sodium. 
     
     
       6. A compound according to claim 1 in which the metal is copper. 
     
     
       7. The zinc salt of 1,1,5,5-tetramethyldithiobiuret.
