75 years after the discovery of borazine by Stock et al., metal atoms could for the first time be introduced as ring components into the borazine framework. The compounds 2 and 3 are formed in the ratio 1:1 in 98% yield from 1 and TiCl 4 . As a result of strong intramolecular TiN interactions, 2 is not planar but can be described as a doubly edge‐bridged Ti 2 N 2 tetrahedron.
