Chloroformate derived Reissert compounds of isoquinoline and of phenanthridine on treatment with base undergo cyclisation with isothiocyanates to give in good yields corresponding imidazoisoquinoline and imidazophenanthroline derivatives.Phthalazine Reissert compound analogues give open chain adducts under the same conditions which can be cyclised to derivatives of the novel imidazophthalazine system by heating in the presence of molecular sieves.When carbon disulphide is the heterocumulene cyclisation is not observed but open chain dithio-ester derivatives can be isolated on alkylation of the intermediate sodium salts.
