ChemInform Abstract: Synthesis and Molecular Structures of Lanthanocene Amide Complexes and Their Catalytic Activity for Addition of Amines to Nitriles.

Abstract

Nitriles. -Three biscyclopentadienyl ytterbium or yttrium amides are prepared. Their catalytic activity in the title reaction depends on the complex metal and the amide group. Best results are obtained with YBA providing monosubstituted N-arylamidines in good to excellent yields for aromatic nitriles and amines, whereas aliphatic substrates are less suitable under the present conditions. -(CAI, T.; CHEN, X.; XU, F.; ZHANG, Y.; YAO, Y.; SHEN*, Q.; J.
