A series of hydrazonyl chlorides bearing an alkenyl chain have been synthesised and treated with silver carbonate.The propensity of the so-formed nitrile imine intermediates to undergo intramolecular cycloaddition is markedly dependent on the length and the flexibility of the chain.The latter also affected the regio- and the stereo-chemistry of the intramolecular process.In certain circumstances, tandem intermolecular-intramolecular cycloadditions took place, to produce large-ring heterophanes.
