pharmaceuticals. However, the direct intramolecular radicalcyclizations of the corresponding amide compounds favor 5-exo products 2. Reports on the radicalcyclization reactions producing 3,4-dihydroquinolin-2-one derivatives are limited. Herein, an efficient tandem reaction combining radical and ionic processes was developed, which provides a practical syntheticstrategy for the synthesis of substituted

A series of p-diethynylbenzene- based molecular wires, Fe-C C-p-C6H2X2-C C-Fe (3) (Fe = FeCp* (dppe)), is prepared and their wire-like performance is estimated on the basis of the K-C and V-ab values. It has been revealed that electron-donating substituents (X) improve the performance. The benzodifuran complex 4 unexpectedly formed from the derivative with X = OH shows the performance comparable to 3. (C) 2009 Elsevier B.V. All rights reserved.

Molecule-based magnetic polymers with high Curie temperature and methods of preparing are provided. In particular, magnetic polymers having repeating units of an electron-donor metallocene-containing monomer covalently bonded to an electron-acceptor monomer having a plurality of unpaired electrons are disclosed. Intrinsically homogeneous magnetic fluids (liquid magnets) and methods of preparing are also provided.

Synthesis and Photoswitching Studies of OPE-Embedded Difurylperfluorocyclopentenes
and hydrolysis furnished 5 in good overall yield. Substituents R1 and R2 in the OPE portion were either electron-withdrawing or electron-donating, and their influence on the photostability and photoswitching characteristics of 7a–e was studied. All resulting molecules show reversible photochromism between the colorless off and the deeply colored on states when irradiated with light of 313 and 576 nm
