C-H activation of arenes has been established as an important strategy for heterocycle synthesis via annulations between arenes and unsaturated coupling partners. However, nitriles failed to act as such a coupling partner. Dioxazolones have been employed as a synthon of nitriles, and subsequent coupling with arenes such as N-sulfinylimines and benzimidates bearing a functionalizable directing group provided facile access to two classes of quinazolines under Co(III)-catalysis.
Clathrate Formers with Allene Structure - Host Compounds, Crystal Inclusion and Structure of a Dioxane Clathrate

The tetraaryl-substituted allenes 1-8 are synthesized, and their properties in crystal inclusion are determined.Dependent on the type and number of the substituents, host compounds result, which have different inclusion properties and clathrate selectivities.Host 1h forms inclusion compounds with a wide range of apolar and relatively polar cyclic guest solvents (26 inclusions altogether), while 2, 4, 5, and 7b form only one or two inclusions.In two-component solvent systems, high inclusion selectivities are found for the host compounds.The crystal structure of the4*dioxane (1:1) clathrate is reported.Relations between structure and inclusion selectivity are discussed.
