A facile reduction of 2-aminopyrimidines with triethylsilane and trifluoroacetic acid
摘要:
2-Aminopyrimidines were facilely reduced to 2-amino-dihydro- or 2-amino-tetrahydropypryrimidines with triethylsilane and trifluroacetic acid in high yields. By controlling the equivalents of reducing reagents and temperature, selective reduction could also be achieved for some substrates. (C) 2004 Elsevier Ltd. All rights reserved.

A method of using a metal complex as an n-dopant for doping an organic semiconducting matrix material in order to alter the latter's electrical characteristics is provided. In order to provide n-doped organic semiconductors with matrix materials having a low reduction potential, while achieving high conductivities, the n-dopant is a neutral electron-rich metal complex with a neutral or charged transition metal atom as a central atom and having at least 16 valence electrons. The complex can be polynuclear and can possess at least one metal-metal bond. At least one ligand can form a π complex with the central atom, which can be a bridge ligand, or it can contain at least one carbanion-carbon atom or a divalent atom. Methods for providing the novel n-dopants are provided.
