Research on Low-Coordinate and Multiply-Bonded Compounds of Heavier Main Group Elements

点击翻译按钮获取中文摘要

We have developed novel sophisticated synthetic strategies for the preparation of highly challenging classes of low-coordinate derivatives of the heavier main group elements (multiply-bonded compounds such as disilynes with silicon-silicon triple bonds, isolable Si-, Ge-, and Sn-centered cations, radicals, and anion-and cation-radicals, Si and Ge heterocycles and their uses as ligands for transition metals etc.). We also performed the detailed analysis of their structural and synthetic properties, and carried out the systematic study of the basic similarities and differences between these new species and their organic analogues.
