Abstract:
Herein, we report the reactivity of a monocoordinate bismuthinidene (1) with various organic azides. The reaction of 1 with p-toluenesulfonyl azide resulted in the formation of an unprecedented, unsupported iminobismuthane (2), which features the shortest reported Bi-N distance of 2.041(3) Å in an iminobismuthane. Conversely, the reaction of 1 with 4-azidobiphenyl resulted in the first example of a species containing a tetraazabismole (BiN4) heterocycle (3). We also highlight that 1 demonstrates catalytic activity, enabling the reduction of a selection of organic azides.

Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
