[{MeAl(μ -F)} N(2,6-iPr C H )] - A Molecular Al-F-N Cage Compound.

In a two-step elimination reaction the molecular Al-F-N cage compound 1 is synthesized from (2,6-iPr C H )NH (ArNH ) and Me AlF under methane evolution. Compound 1 was characterized by means of X-ray structure analysis and can be regarded as a precursor for ternary Al-F-N systems.

Formation of Adamantane-Like Structures by Reaction of Titanocene Fluorides with an Iminoalane.

Fluorine-nitrogen metathesis in the reaction of a cyclic iminoalane with titanocene fluorides results in unexpected cage compounds. Treatment of one of these compounds with diethyl ether leads to 1, which contains a titanium-nitrogen double bond stabilized intramolecularly by fluorine.
