Anomalous products from 1,2,5-triaza- and 1,5-diaza-pentadiene thermolyses: formation of amidines and pyrroles, respectively
Abstract
Gas-phase thermolysis of the dimethylamino-azoalkene (1) gives the formamidine (2) by loss of HCN: in contrast, the related 1,5-diazapentadiene (4) under more forcing conditions gives aniline (30%) and N-methyl-pyrrole (43%).
