rhe highly reactive silyltriflates are valuable reagents in organosili
con chemistry. Triflate derivatives of polysilylacetylenes [(CF3SO3)RS
i-C=C-]n and polysilyldiacetylenes [(CF3SO3)Rsi-C=C-C=C-]n are obtaine
d by reaction of the corresponding allyl derivatives with trifluoromet
hane-sulfonic acid. The compounds show a high reactivity with nucleoph
iles. The reactions lead to new functional substituted polysilylacetyl
enes. The polymers are characterised by NMR-spectroscopy (Si-29, C-13,
H-1).
