Abstract Nitration of benzocyclobutene (1) using acetyl nitrate, generated in situ by a continuous process, in the presence of montmorillonite K 10 clay gives 3-nitrobicyclo[4.2.0]octa-1,3,5-triene (2) in 60% yield which is a two-fold increase over the known methods.

itroacetanilide and 4-acetamido-5-nitrobenzocyclobutene, and thence the 4-amino-5-nitro compound. This last, on diazotization and then reduction, gives 4-nitrobenzocyclobutene, and on diazotization followed by hydrolysis and acetylation, 4-acetamido-5-acetoxybenzocyclobutene. The same acetamidoacetoxy compound is also formed by diazo coupling, reduction and then acetylation of 4-hydroxybenzo-cyclobutene
