A new type of mesoporous-C4N4-based catalyst (n-butBr/mp-C3N4) was prepared by simple grafting of n-bromobutane. The N2 adsorption–desorption and X-ray diffraction characterizations indicate that, in comparison with the parent mp-C3N4, the textual and structural properties have been well retained by n-butBr/mp-C3N4. In the cycloaddition of CO2 with propylene epoxide, the n-butBr/mp-C3N4 exhibits high catalytic conversion as well as a high selectivity to propylene carbonate. The maximum TOF value obtained over n-butBr/mp-C3N4 is 10.7 h−1 at 6 h under 140 °C, which compares favorably to other reported C3N4-based catalysts. In addition to n-bromobutane, mp-C3N4 materials grafted with other alkyl halides also provide high catalytic activities. According to the Fourier transform infrared and X-ray photoelectron spectroscopy measurements, it is speculated that the catalytic active sites of n-butBr/mp-C3N4 are uncondensed amines and Br anions which originate from the reaction between n-bromobutane and the N-containing heterocycles of mp-C3N4.

Efficient synthesis of supported proline catalysts for asymmetric aldol reactions

Proline has been grafted onto silica supports in a single step by reacting trans-4-hydroxy-L-proline with chloropropyl tethers, without the use of protecting groups for the proline amine and carboxylic acid functional groups. The resulting catalysts have been characterised to show that grafting is through reaction with the 4-hydroxy group. The catalysts have been tested in an asymmetric aldol reaction, and shown to be both more active and more enantioselective than equivalent catalysts prepared using a protection/deprotection route for the proline grafting step.

A sustainable flow chemistry process for the hydration of nitriles, whereby an aqueous solution of the nitrile is passed through a column containing commercially available amorphous manganese dioxide, has been developed. The product is obtained simply by concentration of the output stream without any other workup steps. The protocol described is rapid, robust, reliable, and scalable, and it has been applied to a broad range of substrates, showing a high level of chemical tolerance.

Red wine compound could help seniors walk away from mobility problems

ClinicalNews

PHILADELPHIA, Aug. 19, 2012 — In a stride toward better health in later life, scientists reported today that resveratrol, the so-called “miracle molecule” found in red wine, might help improve mobility and prevent life-threatening falls among older people. The finding, believed to be the first of its kind, was presented today to some 14,000 scientists and others gathered at the 244thNational Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

The researchers say this report — based on studies of laboratory mice — could lead to the development of natural products designed to help older Americans live safer and more productive lives.

“Our study suggests that a natural compound like resveratrol, which can be obtained either through dietary supplementation or diet itself, could actually decrease some of the motor deficiencies that are seen in our aging population,” said Jane E. Cavanaugh, Ph.D., leader of the research…

.Continuous preparation of arylmagnesium reagents in flow with in-line IR monitoring

.Continuous preparation of arylmagnesium reagents in flow with in-line IR monitoring

A newly developed microscale ReactIR flow cell was used as a convenient and versatile inline analytical tool for Grignard formation in continuous flow chemical processing. The LiCl-mediated halogen/Mg exchange reaction was used for the preparation of functionalized arylmagnesium compounds from aryl iodides or bromides. Furthermore, inline IR monitoring was used for the analysis of conversion and possible byproduct formation, as well as a potential tool for elucidation of mechanistic details. The results described herein indicate that the continuous flow systems are effective for highly exothermic reactions such as the Grignard exchange reaction due to fast mixing and efficient heat transfer.
