Abstract
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.
