Abstract

Compounds of the formula ##STR1## in which R is alkyl, furanyl, phenyl and isopropenyl and R¹ and R² are alkyl, or their amine salts and their use in retarding the ripening of picked fruits, vegetables and other merchantable materials of plant origin.

Claims

1. Compounds having the structural formula ##STR10## in which R is alkyl having 1 to 12 carbon atoms, furanyl, phenyl and isopropenyl, R¹ and R² are independently alkyl having 1 to 4 carbon atoms and their salts wherein the anion is chloride, bromide, acetate, sulfate or phosphate.

2. The compounds and their salts of claim 1 wherein R is alkyl having 4 to 10 carbon atoms, 2-furanyl, phenyl and isopropenyl, R¹ and R² are both ethyl.

3. The compound and its salts of claim 1 wherein R is isopropenyl, R¹ is ethyl and R² is ethyl.

4. The compound and its salts of claim 1 wherein R is n-decyl, R¹ is ethyl and R² is ethyl.

5. A method for retarding the ripening of picked fruits, vegetables and other merchantable materials of plant origin comprising contacting said fruits, vegetables and other merchantable material of plant origin with an amount effective to retard ripening of a compound having the structural formula ##STR11## in which R is alkyl having 1 to 12 carbon atoms, furanyl, phenyl, and isopropenyl, R¹ and R² are independently alkyl having 1 to 4 carbon atoms and their salts wherein the anion is chloride, bromide, acetate, sulfate or phosphate.

6. A method of claim 5 wherein R is alkyl having 4 to 10 carbon atoms, 2-furanyl, phenyl and isopropenyl, R¹ and R² are both ethyl.

7. A method of claim 5 wherein R is isopropenyl, R¹ is ethyl and R² is ethyl.

8. A method of claim 5 wherein R is n-decyl, R¹ is ethyl and R² is ethyl.
