One for two: A zirconium compound combined with a main‐group alkaline earth metal through an oxygen bridge has been synthesized. A number of primary and secondary aminoalkenes were successfully converted into cyclic products using this heterobimetallic complex as catalyst. The calcium center activates primary aminoalkenes, and the zirconium center activates secondary aminoalkenes.
