Abstract:
Reactions of the boron halides with organic halides
and organo-silicon compounds have been investigated. The
results show exchange of halogens between the BX3 (X = Br# 1)
and the organic halidef exchange of the halogen of the C-X
bond being proved. The rates of halogen exchange vary.
Reaction of the heavier halides with organo-silicon compounds
indicated that the silicon-carbon bonds ruptured in the
absence of electronegative atom attached to the silicon. The
presence of an electronegative atom (halogen or oxygen)
attached to the silicon causes the bond between the silicon
and the electronegative atom to be preferentially broken.
Products of exchange reactions of the boron halides and the
organic halides or the organo-silicon compounds were studied
by use of 1H NMR and GC/MS. From these results some possible
mechanisms for the exchange reactions are postulated, but
further work is indicated to prove the real courses of the
reactions
