Cationic rhodium complexes of certain nitrogen-containing ligands exhibit excellent activity in the addition of arylboronic acids to aldehydes. The counterion had a notable effect with the weakly coordinating carborane anion affording a highly active catalyst.

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.
