Aromatic amidines as fluorogenic reagents for reducing carbohydrates.

The estimation of aromatic amidines.

The determination of aromatic amidines in plasma and urine.

Certain aromatic amidines have been reported to be useful chemotherapeutic agents for the treatment of leishmaniasis, trypanosomiasis, and babesiasis (1). Pharmacological and clinical studies of these compounds have been handicapped by lack of suitable methods for the determination of aromatic amidines in plasma and urine. Recently Fuller (2) described a method which is based upon a reaction be...

Iron-catalyzed alkylations of aromatic grignard reagents.

Significance: The development of iron-catalyzed cross-coupling reactions is an extremely promising field of research, taken into account the importance of this method for current organic synthesis and the multiple problems connected with commonly used Pdand Ni-catalyzed processes. The group of Cahiez reported the first iron-catalyzed alkyl–aryl cross-coupling reaction, suitable for industrial l...

The effectiveness of aromatic o-diamines as chromogenic reagents for PtII determination in aqueous micellar solutions

reagents for PtII determination in aqueous micellar solutions has been reported.1 It is believed that complexation of the PtII ion with these ligands is accompanied by a unique redox reaction of the PtII complexes (Scheme 1). These complexes exhibit peculiar and huge absorption having a molar absorptivity (ε >104 to 105 l mol–1 cm–1) in the near-infrared (NIR) region of 700 to 900 nm when they ...

Efficient O‐Functionalization of Carbohydrates with Electrophilic Reagents

Novel methodology for O-functionalization of carbohydrate derivatives has been established using bench-stable and easily prepared iodonium(III) reagents. Both electron-withdrawing and electron-donating aryl groups were introduced under ambient conditions and without precautions to exclude air or moisture. Furthermore, the approach was extended both to full arylation of cyclodextrin, and to trif...
