Abstract

The acylation of N-substituted 3-methyl-1H-1,2-diazaphenalenes of the naphthalene and acenaphthene series with trifluoroacetic anhydride gave mono- and diacylated products. Despite the presence of a bulky substituent on the pyrrole type nitrogen atom, the trifluoroacetyl group entered the peri position with respect to that substituent. The product structure was confirmed by X-ray analysis.
