Kadethrin (58769-20-3) |
| Hazard Information | Back Directory | [Uses]
Kadethrin is used to control household pests, particularly houseflies,
mosquitoes and cockroaches. It is normally used in combination
with other pyrethroid insecticides and synergists. | [Metabolic pathway]
Kadethrin is used almost wholly indoors and therefore little has been
published on its environmental fate. Information on its photodegradation
and metabolism in rats has been reported. | [Degradation]
Kadethrin is unstable to heat and it is rapidly decomposed by light. It
is hydrolysed in aqueous alkaline solution to (E)-(1R)-cis-2,2-dimethyl-3-
(2-oxothiolan-3-ylidenemethyl)cyclopropanecarboxylic acid (2), 5-benzyl-
3-furylmethanol (3) and its thiolactone ring-opened derivative (5)
(Scheme 1).
Products of photodecomposition have been reported by Ohsawa and
Casida (1979). Photo-hydrolysis of kadethrin occurs on sunlight irradiation
affording 2 and 5 and 5-benzyl-3-furancarboxylic acid (4), presumably
via the alcohol (3). cis-trans Isomerisation of the cyclopropane ring
and E-Z interconversion about the double bond was also noted. Thus,
from the lRcisE isomer (kadethrin), all of the possible isomers were found
to varying degrees (ie. 1RScis-trans-E-Z mixtures).
Photo-hydrolysis products (e.g. 2 and 5) were also found aS isomers.
The facility of the isomerisation process was considered to be due to
resonance stabilisation of a triplet diradical, one form of which (6) is
shown in Scheme 1. Kadethrin also yielded a lactone (7) derived from the
cyclopropane ring. Photo-oxidation of the alcohol moiety analogous to that reported for resmethrin was also found. The hydroxylactone (8) and
the benzyloxylactone (9) were reported (but the hydroxycyclopetenolone
[resmethrin, 61) was absent. |
