A boronate-assisted fluorogenic chemosensor in a solid phase is developed, selectively to detect the mycolactones produced by the human pathogen Mycobacterium ulcerans.


Diastereoselective HOTf-catalyzed three-component one-pot 1,3-dipolar cycloaddition of -diazo ester, nitrosobenzene and electron-deficient alkene
Zhen-Jiang Xu, Di Zhu, Xiaofei Zeng, Fei Wang, Bin Tan, Yuxuan Hou, Yunbo Lv and Guofu Zhong,  Chem. Commun., 2010
DOI: 10.1039/b924575h

graphical abstract image (ID: b924575h)

A novel, diastereoselective cycloaddition of -diazo ester, nitrosobenzene and electron deficient alkene catalyzed by HOTf provides functionalized isoxazolidines in high yields, which is simple to operate and tolerant to moisture/oxygen.


Reversible, solid state capture of carbon dioxide by hydroxylated amidines
Myungsook Kim and Ji-Woong Park,  Chem. Commun., 2010
DOI: 10.1039/b921688j

graphical abstract image (ID: b921688j)

Hydroxylated amidine derivatives can capture, store, and release CO2 reversibly in the solid state in a quantitative manner under clean and dry conditions at ambient temperature.


Organometallic control at the nanoscale: a new, one-pot method to decorate a magnetic nanoparticle surface with noble metal atoms
Nabil Atamena, Diana Ciuculescu, Gilles Alcaraz, Alevtina Smekhova, Fabrice Wilhelm, Andrei Rogalev, Bruno Chaudret, Pierre Lecante, Robert E. Benfield and Catherine Amiens,  Chem. Commun., 2010
DOI: 10.1039/b925054a

graphical abstract image (ID: b925054a)

A novel cascade of reactions is designed to control in situ the deposition of noble metal islands (e.g. Rh) on top of nanoparticles of a 3d metal (e.g. Fe, Co).
