Synthesis of difunctional borasiloxanes and their behavior in metathesis reactions
摘要:
New divinyl- and diallyl-borasiloxanes have been synthesized in good yield from corresponding boronic acids. They have been characterized by H-1-, C-13-, Si-29- and B-11-NMR, as well as by MS. Their behavior in metathesis reactions initiated by two different catalysts ([RhCl(COD)](2) for vinylsiloxanes and [Mo] Schrock's catalyst for allylsiloxanes) has been studied. This has led to new cycloborasiloxanes that have been characterized. (C) 1998 Elsevier Science S.A. All rights reserved.
