Cover Picture: Modular Synthesis of Triarylmethanes through Palladium‐Catalyzed Sequential Arylation of Methyl Phenyl Sulfone (Angew. Chem. Int. Ed. 3/2014)

Triarylmethanes were prepared in three steps from phenyl methyl sulfone, as described by M. Nambo and C. M. Crudden in their Communication on page 742 ff. After two selective CH arylation reactions, the third aromatic ring was introduced through a novel arylative desulfonation. This sequence permits the synthesis of a wide variety of unsymmetric triarylmethanes from a simple, readily available starting material.

X⋅⋅⋅H Hydrogen Bonds Unconventional CH⋅⋅⋅X hydrogen bonds are strong enough to drive supramolecular polymerization and gelation processes, as described by G. Fernández et al. in their Communication on page 700 ff. The molecular arrangement is maintained in the crystalline state.1 Shape-Dependent Lysis In their Communication on page 842 ff., J. M. Cooper et al. describe the selective lysis of red blood cells by an electric field. The selectivity results from the shape of the blood cells.1 Ketone Alkylation T. J. Donohoe et al. describe in their Communication on page 761 ff. the use of methanol as an alkylating reagent in a rhodium-catalyzed reaction to generate branched alkyl products from aromatic and aliphatic ketones under mild conditions.1
