Abstract
Fluorinated alkene compounds useful for and methods of controlling nematodes, insects, and acarids that prey on agricultural crops. Polar compounds, for example, 3,4,4-trifluoro-3-butene-1-amine or 3,4,4-trifluoro-3-butenoic acid, are particularly useful for systemic control of pests. Novel method and intermediates for the preparation of 3,4,4-trifluoro-3-butene-1-amine are also provided.
Claims21
A compound having the structure ##STR154## wherein R.sub.11 is --OR.sub.12, SR.sub.12, halogen, --NHOH, or --NR.sub.12 R.sub.13 ;
- each of R.sub.12 and R.sub.13 is independently hydrogen;
- an alphatic or an aromatic group, optionally substituted with at least one group selected from the group consisting of hydroxy, alkoxy, halo, nitro, amino, thiol, alkylthio, carboxyl, alkoxycarbonyl, and phenyl;
- a C.sub.1 -C.sub.12 aliphatic amine, optionally substituted with at least one group selected from the group consisting of hydroxy, alkoxy, halo, nitro, amino, thiol, alkylthio, carboxyl, alkoxycarbonyl, and phenyl;
- or a C.sub.2 -C.sub.12 aliphatic carboxylic acid, optionally substituted with at least one group selected from the group consisting of hydroxy, alkoxy, halo, nitro, amino, thiol, alkythio, carboxyl, alkoxycarbonyl, and phenyl;
- or R.sub.12 and R.sub.13 taken together with the N or R.sub.11 are a protein amino acid or a cyclic group selected from the group consisting of morpholine, piperidine, piperazine, or pyrrolidine, optionally substituted with at least one group selected from the group consisting of hydroxy, alkoxy, halo, nitro, amino, thiol, alkylthio, carboxyl, alkoxycarbonyl, and phenyl;
- or an agronomically acceptable salt thereof.
A method of systemically controlling nematode, insect or acarid infestation of a plant, comprising applying to a plant locus an effective amount of a compound having the structure ##STR155## wherein R is a group that has or is transformed after application to have a polarity providing phloem mobility without reducing infestation controlling effectiveness.
