Photoaddition of silyl ketene acetal to [60]fullerene. Synthesis of α-fullerene-substituted carboxylic esters
Abstract
Photoaddition reaction of silyl ketene acetal to [60]fullerene takes place at low temperature in wet toluene to afford α-fullerene-substituted carboxylic esters in good yields instead of the expected [2 + 2] cycloadduct.
