Mono- and penta-addition of enol silyl ethers to [60]fullerene.
The reaction of 1-alkoxy-1-siloxyethene with [60]fullerene in 20% DMSO/chlorobenzene at ambient temperature under an oxygen atmosphere gave a penta-addition product, while the reaction of 1-alkoxy-1-siloxyalkenes or 1,2-siloxyalkenes under argon gave monoaddition products. The new method has merits over the previously reported syntheses of these compounds in that the synthesis does not require the use of heavy metals or photolysis conditions, and it can be carried out under simple and mild conditions.
