End-On Nitrogen Insertion of a Diazo Compound into a Germanium(II) Hydrogen Bond and a Comparable Reaction with Diethyl Azodicarboxylate

摘要

The reaction of diazoalkanes with transition metals has a long history in the cyclopropanation of olefins. Moreover, metal carbene complexes play an important role in olefin metathesis, C-H bond activation, and the synthesis of reactive ylides. In all these examples, diazoalkane either interacts with the metal center to form a metal diazoalkane complex or subsequently releases dinitrogen from diazoalkane to form the metal carbene complex. In contrast, the reaction of diazoalkane with main group metals is scarcely known in literature.
