| —— | 1-methyl-5-nitro-1H-pyrrole-2-carbonitrile | 2853-30-7 | C6H5N3O2 | 151.125 |
The 2-nitriles of pyrrole and 1-methylpyrrole have been prepared by the dehydration of the corresponding aldoximes. These compounds have been nitrated and the ratios of 4- and 5-nitro isomers have been determined. The 2-cyano group appears to be less strongly "meta"-directing (i.e. toward the 4-position) during nitration in the pyrrole series than in the benzene ring.
