In acidic media, aldrin' and its dechloro-derivatives 3 undergo Wagner-Meerwein type rearrangements to form derivatives of isodrin: an analogous rearrangement of dieldrin has not yet been reported.
with various acids is reported to give either 4-oxo-4,5-dihydroaldrin 485
or the normal trans products resulting from opening of the epoxide ring 6 .
This letter reports a Wagner-Meerwein type skeletal rearrangement of dieldrin in either acetic anhydride/sulfuric acid or boron trifluoride/methanol mixtures to give compounds of general formula VII as the major products.
A mixture of purified dieldrin and acetic anhydride/sulfuric acid (100/l) was refluxed for one hour to yield, after isolation', three pure crystalline
