  名称：

  Synthese und Einsatz von trägerfixierten Katalysatoren zur heterogen-katalysierten SiSi-Bindungsspaltung in Chlormethyldisilanen

  摘要：

  Lewis bases like bis(dimethylamide)phosphoryl compounds (2, 5-7), N-heterocycles (8 and 9) and N,N-dialkylamina-3-propylsilanes bearing alkoxy groups are grafted via siloxane bonds onto silica carriers. The preparation and characterisation of 5-9 are reported. The grafted bis(dimethylamide)phosphoryl compounds (2, 5-7) and N-heterocycles (8, 9) are efficient catalysts for the disproportionation of chloromethyldisilanes into chloromethyloligosilanes and chloromethylsilanes. Grafted N,N-dialkylamino-3-propylsilyl compounds heterogeneously catalyze the Si-Si bond cleavage of the disilanes with hydrogen chloride at 170 degrees C in excellent yields. A mixture of chloromethylmonosilanes is obtained. This reaction is also performed under pressure.
