A simple and general visible-light-mediated oxidation of organoboron compounds has been developed with rose bengal as the photocatalyst, substoichiometric Et3N as the electron donor, as well as air as the oxidant. This mild and metal-free protocol shows a broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this method is demonstrated on the stereospecific aerobic oxidation of organoboron compounds.

The reversible reaction of an aldehyde with a hydroxylamine affords a nitrone which is capable of forming a stiff gel with chloroform at concentrations as low as 0.20 wt% (6 mM). The gelator forms dynamically from its constituents and the gel assembly can be degraded in a controlled manner through a recognition-mediated reaction that targets the nitrone component of the gel network.

Despite their great diversities, 2D-shaped macrocycles that can serve as the organogelators have been surprisingly rare; two planar macrocyclic fluoropentamers designed by us were highly able to gelate organic solvents, largely derived from their strong tendency to form 1D stacked fibrillar structures stabilized by both interplanar H-bonds and π-π stacking forces.
Crystallographic realization of the mathematically predicted densest all-pentagon packing lattice by C5-symmetric "sticky" fluoropentamers

Regular pentagonal adhesive tiles were obtained by designing a cyclic fluoropentamer with an internal CF...HN H-bonded network and "sticky" edges that can glue the molecules together through intermolecular CArH...O=C H bonds. In the crystal they form the mathematically predicted densest all-pentagon 2D lattice with a packing density of 0.921 (see picture). Copyright

(Chemical Equation Presented) A general, mild, and efficient method for the hydrolysis of organotrifluoroborates to unveil boronic acids using silica gel and H2O was developed. This method proved to be tolerant of a broad range of aryl-, heteroaryl-, alkenyl-, and alkyltrifluoroborates as well as structurally diverse aminomethylated organotrifluoroborates.As anticipated, electron-rich substrates provided the corresponding boronic acids more readily than electron-poor substrates, owing to the resonance-stabilized difluoroborane intermediate. The method developed was expanded further for the conversion of organotrifluoroborates to the corresponding boronate esters. 2009 American Chemical Society.
