摘要：

The use of carbosilane based dendrimers as molecular scaffolds for the attachment of organomettallic Ni "pincer" complexes that are active as a catalyst in the Kharasch addition reaction is described. It is shown that increasing steric crowding at the dendrimer periphery results in decreased catalyst activity, most likely as a consequence of an intramolecular redox process. Furthermore, preliminary investigations have shown that the application of this catalyst system in a continous process using a membrane reactor is possible. (C) 1999 Elsevier Science B.V.
