Addition of cyclopentadiene to unsubstituted O-acyl-1,4-benzoquinone monooximes or their 2- or 3-methyl derivatives across the double bond of the quinone ring yielded the only endo-Z isomer, in spite of the possibility for isomerization around the C=N bon
Chlorination and Bromination of 4-Arylsulfonyloxyimino-2,5-Cyclohexadien-1-Ones and 1,4-Di(arylsulfonyloxyimino)-2,5-Cyclohexadienes
