실험 절차

An alternative process is that wherein a 3- or 4-halobenzocyclobutene reactant is treated with a phthalimide or maleimide to produce a 3- or 4-phthalimido-or maleimidobenzocyclobutene. When phthalimide or maleimide is monomeric, for example, phthalide or maleimide themselves, the product can be cleaved by reaction with an amine to produce a corresponding aminobenzocyclobutene. A preferred amine for this purpose is hydrazine, preferably hydrazine hydrate.
