Gm. Fingerling et H. Parlar, SPECTROSCOPIC CHARACTERIZATION OF 7B,8C,9C-TRICHLOROCAMPHENE-2-ONE FORMED FROM TOXAPHENE COMPONENTS IN AN ANAEROBIC SOIL, Journal of agricultural and food chemistry, 45(10), 1997, pp. 4116-4121
A cyclic ketone, formed from the toxaphene components Toxicant A (Parl
ar No. 42) and Toxicant B (Parlar No. 32) in a flooded loamy silt in l
aboratory experiments, has been isolated, and its structure has been c
haracterized. The product has been shown to have a camphenone skeleton
, possibly formed via a Wagner-Meerwein rearrangement. The structure h
as been identified as 7b, 8c, 9c-trichlorocamphene-2-one. This is the
first time that an oxygen-containing product as conversion product of
a toxaphene component has been isolated. Comparison with the behavior
of single toxaphene components in autoclaved soil points out that the
7b,8c,9c-trichlorocamphene-2-one is the result of biotransformation.
