NiII tetrahydronorcorroles: antiaromatic porphyrinoids with saturated pyrrole units†
Abstract
While hydrogenated porphyrins are abundant in natural and synthetic compounds, antiaromatic hydrogenated porphyrinoids have not been synthesized to date. Here, we report bacteriochlorin-like NiII tetrahydronorcorrole complexes as the first examples of antiaromatic porphyrinoids that contain saturated pyrrole units.
