Article abstract of DOI:10.1021/jo00317a011

The addition of bromine and chlorine to 1,4-benzoquinone 4-(O-methyloxime) (1) under kinetic control and of cyclopentadiene to 1 or the 2-methyl derivative (3) under conditions where isomerization about the C=N bond can occur gives rise to products in whi
