Regioselective Oxidative Ring Cleavage of Antiaromatic Nickel(II) Norcorrole to Dialkoxybis(dipyrrin)s.

Invited for this month's cover is the group of Prof. Dr. Hiroshi Shinokubo at Nagoya University, Japan. The front cover shows the oxidative ring opening reaction of an antiaromatic porphyrinoid, norcorrole, into dipyrrin dimers. The background with the map of Japan represents the venue of ISNA-18, which will be held in Sapporo, Japan in July 2019. Read the full text of the article at 10.1002/cplu.201900068.
