Zur Synthese von Siloxanen XI. Spaltung von Siloxanen durch Bortrifluorid

The cleavage of siloxane bonds by BF3 was investigated kinetically by 1H NMR spectroscopy.The reactions could be evaluated by use ofa pseudo-first order rate law, when a sufficiently large excess of BF3 was used.The order with respect to BF3 was found to be 4.7.The rate constants obtained could be correlated to ?*- values with a ρ*-value of -1.0.The ?*-value found previously by 29Si NMR spectroscopy for the Me3SiO group of 0.35 was confirmed.

REACTIONS IN THE CHLOROSILANE-SILANOL-SILOXANE SYSTEM

We obtained the first ?*-values and ES-values for siloxy groups by spectroscopic and kinetic methods.Detailed mechanistic investigations are performed on the hydrolysis of chlorosilanes, the cleavage of Si-O-Si bonds by HCl, and the substituent exchange reaction between silanols and chlorosilanes.
