ethyl)imine when treated with lithium aluminum hydride (LAH), followed by a mild work-up. A plausible mechanism of this reductive coupling was inferred from a series of experiments, including 27Al-NMR, deuteration experiments, and the reduction of variously substituted cyanopyrroles. The mechanism, a metal chelate mediated dimerization, may be the key to understanding porphocyanine synthesis via the
