Di(hydroperoxy)adamantane adducts: synthesis, characterization and application as oxidizers for the direct esterification of aldehydes.

The di(hydroperoxy)adamantane adducts of water (1) and phosphine oxides -TolPO·(HOO)C(CH) (2), -TolPO·(HOO)C(CH) (3), and CyPO·(HOO)C(CH) (4), as well as a CHCl adduct of a phosphole oxide dimer (8), have been created and investigated by multinuclear NMR spectroscopy, and by Raman and IR spectroscopy. The single crystal X-ray structures for 1-4 and 8 are reported. The IR and P NMR data are in accordance with strong hydrogen bonding of the di(hydroperoxy)adamantane adducts.

Mechanical Control of Periodic Precipitation in Stretchable Gels to Retrieve Information on Elastic Deformation and for the Complex Patterning of Matter.

Material design using nonequilibrium systems provides straightforward access to complexity levels that are possible through dynamic processes. Pattern formation through nonequilibrium processes and reaction-diffusion can be used to achieve this goal. Liesegang patterns (LPs) are a kind of periodic precipitation patterns formed through reaction-diffusion.

Iodosylbenzene Coordination Chemistry Relevant to Metal-Organic Framework Catalysis.

Hypervalent iodine compounds formally feature expanded valence shells at iodine. These reagents are broadly used in synthetic chemistry due to the ability to participate in well-defined oxidation-reduction processes and because the ligand-exchange chemistry intrinsic to the hypervalent center allows hypervalent iodine compounds to be applied to a broad array of oxidative substrate functionalization reactions. We recently developed methods to generate these compounds from O that are predicated on diverting reactive intermediates of aldehyde autoxidation toward the oxidation of aryl iodides.
