Notes:
Clathrate Formers with Allene Structure - Host Compounds, Crystal Inclusion, and Structure of a Dioxane ClathrateThe 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 the 4.dioxane (1:1) clathrate is reported. Relations between structure and inclusion selectivity are discussed.
