Primary photoproducts of furan-2-carbonitrile and N-methylpyrrole-2-carbonitrile: trapping by methanol addition
Abstract
Irradiation of furan-2-carbonitrile and of N-methylpyrrole-2-carbonitrile in methanol yielded, respectively, trans-3-formly-2-methoxycyclopropane-1-carbonitrile and N-methyl-3-methoxy-5-azabicyclo[2,1,0]pentane-1-carbonitrile as primary photoproducts, indicating as intermediate species a cyclopropenecarboxaldehyde for furan and an azabicyclopentene for pyrrole.
